Concrete in Cold Weather Guidelines

Roadstone

 

During extremely cold weather concrete (particularly fresh and early age concrete) can be severely damaged by frost and ice. When fresh concrete cools below 0ºC the water in the mix freezes and expands which causes cracking internally and blistering of the surface. Mature concrete that is saturated can also be seriously affected by low temperatures.

Certain precautions can be taken to minimise and possibly prevent frost damage to concrete and the following advice whilst not exhaustive will help protect concrete against frost damage.
Further guidance can also be got from the Irish Concrete Federations publication “Guidelines for Concreting in Cold Weather” available on www.irishconcrete.ie

Effects of cold weather on unprotected concrete
• If there is a risk of frost at night it is essential to protect fresh concrete from freezing.
• Fresh concrete strength must reach 5N/mm² to avoid the effects of frost damage.
• Concrete temperature must be kept at or above 5ºC for the first 48 hours to achieve this.
• Low temperatures will slow down concrete strength development for several weeks.
• Strength development is further reduced during cold weather if GGBS or PFA is used.
• Striking times of formwork must be extended during periods of cold weather.
• External slabs, yards and driveways are particularly vulnerable because they have a large surface area and thin section which allows heat to escape rapidly. Particular precautions must be taken to prevent frost damage to these areas.
• While it is common practice to apply de-icing agents such as salt on concrete surfaces to clear ice and snow during winter, these in themselves can damage the concrete surface that they are applied to. Ammonia based de-icing agents are particularly aggressive and should not be used as they can severely damage concrete surfaces.

Precautions to be taken when concreting in cold weather
• Specifications recommend that concreting should not start when the air temperature is 5ºC and falling and should only begin when the temperature is at 3ºC and rising.
• Fresh concrete should never be placed on or against frozen ground.
• Reinforcing bars and shuttering must be free of ice and snow. Cover and insulate the concrete where possible.
• If concrete has to be placed it should be organised so that it is done as quickly as possible.
• Frost blankets should be used to provide insulation and protection for exposed concrete surfaces.
• Wind breaks will reduce wind chill and evaporation and help lower heat loss especially from slabs.
• Heaters may be necessary to provide continuous heating to the concrete to maintain heat.
• Increasing the cement content or grade of concrete will generate more heat in the concrete; consider the use of air entrainment, polypropylene fibres or accelerator.
• The Irish Standard for Concrete : IS EN 206, recommends using C30/37 (37N) air entrained or C40/50 (50N) concrete where wet horizontal surfaces are exposed to significant freeze/thaw cycles.

Quarry water is much colder than rivers, lakes or the sea – you could die from ‘Cold Shock’ in less than 2 minutes

stay-safe-around-quarries

 

Cold shock can cause you to gasp and drown immediately or can lead to hypothermia, making it very hard to breath. Assuming you survive the cold shock, the drop in temperature causes finger stiffness (making it difficult to climb out), reduced coordination (making it difficult to swim/tread water) and general muscle weakness. It is impossible to help yourself. If cold shock and the reduced physical capabilities don’t result in drowning, hypothermia may kill you.

Quarries are dangerous:

  • Deep water may contain hidden currents or submerged plants which can drag you under
  • Submerged abandoned machinery/car wrecks which you can impale yourself on if jumping in
  • Underwater ledges/ recesses where you can become trapped
  • Dead animals/excrement cause disease
  • Pollution/rubbish causing eye and skin irritations, stomach problems, fungal infections and rashes
  • Poisonous/toxic algae

Roadstone wins at the Irish Concrete Society Awards

architectural concrete, fair faced concrete

Roadstone was delighted to win an award as major supplier to The Cliffs of Moher Coach Park Reception Building at the recent Irish Concrete Society Awards.

The design and construction of the building demonstrates a fantastic visual and practical approach to building with concrete.

A quote from the jury describes the building very well:

“In the sensitive landscape along the coast of Clare to which visitors flock to view the Cliffs of Moher, this project seeks to minimise its visual impact on the setting, creating a sunken enclosure of concrete, incorporating reception facilities for the various coach companies serving the site.

Concrete is cleverly used to hold back the earth enabling the necessary accommodation to be concealed in a mounded form. Benefiting from the inherent strength, robustness and resilience of concrete, its comprehensive use seems particularly appropriate here.

Carefully detailed fair-faced concrete is used extensively in the floors, walls and ceilings both internally and externally, treated with various finishes from exposed aggregate to highly polished, according to its location. Artificial lighting is hidden in niches carved out of the concrete, whilst canted sky windows are crafted to allow daylight into the concealed interior.”

 

Roadstone sponsors Trowel Ready Mortar for the 2019 National Bricklaying Final

Roadstone was delighted to sponsor Trowel Ready Mortar for the 2019 National Bricklaying Final at Ireland Skills Live in the RDS.

“The mortar was a success, the trucks arrived on time each morning.  The consistency and workability of the mortar was second to none..” Brian Conville, Ireland Skills Live

Congratulations to the overall winner Jason Shanahan and all of those who took part in the competition.

“The Roadstone TRM mortar at the National Skills Competition was ideal for the brickwork project we had to build, the mortar was nice and workable and had a nice creamy consistency to it which made building the project just that bit easier for us. It was very consistent when going off which made it very easy for us to time the pointing of the brick in the competition this allowed us to build as much as we could and yet still be able to point up the brickwork to our desired finish.

The mortar when pointed was very aesthetically pleasing to the eye and this allowed us to get as much points for the overall appearance of our projects in the competition. Overall the mortar supplied was perfect for the job at hand and I could definitely see myself using more of the Roadstone mortar for future jobs”.

 – Jason Shanahan, 2019 National Bricklaying Competition Winner

Jason Shanahan, 22 year old from Cork, completed the Phase 4 and 6 of his apprenticeship in TUDublin formerly DIT.

There was a total of six competitors in the 18 hour competition.  The aim of the exam was to test their ability to read and understand a drawing along with the basics of bricklaying i.e. rang, gauge, measurements, level, plump, details and the overall visual look of the job.

This was made a lot harder due to the pressure that comes with competition and being watched by large crowds including the President of Ireland Michael D Higgins, who made sure to inspect the high level of workmanship during his visit to the event.

The future of rainwater management – Irish Building Magazine

WATER WORKS

The drainage solution of the future, a sustainable urban drainage system (SuDS) is an alternative to the traditional pipes, gullies and culverts approach to a development and drainage strategy. “If you could imagine a green field,” says Michael Vaughan of Roadstone, “you’d have about a 10% water runoff. A built-up, hard landscape area could have up to 50% runoff. The sheer amount of runoff water you have to deal with is immense when you are constructing high-density developments.” Managing the water on site, minimising its runoff, infiltrating the water for passive treatment and controlling its discharge rate are the key elements of this kind of drainage. The Roadstone Aquaflow paving system provides a practical solution to SuDS.

Michael Vaughan says that the fact of the matter is that while there are drainage systems in place throughout the country, we can’t keep feeding into them forever more. “I think this is an issue the entire country will be dealing with going forward. The way we address this issue is by dealing with the water close to its source,” he explains. By doing that, we can use SuDS paving which allows the water to filter through the paving into a sub-structure, which is designed, and you have controlled release of the water back into the ground.” The Roadstone Aquaflow SuDS allows rainwater to infiltrate through a permeable block paved surface into a unique sub-base before being released in a controlled manner into the ground or storage tanks for reuse or delayed discharge. The system is capable of handling rainfall up to 4,500mm per sq.m per hour.

The water leaving the Aquaflow system is cleaned by filtration and microbial action and can be used for secondary non-potable uses such as flushing toilets and watering soft landscapes. A further advantage of Roadstone’s Aquaflow system is that roof water can be drained directly into the sub-base through a dispersion chamber. A good example of the efficient use of SuDS is the 21,000 sq.m car park with a SuDS system used by Kildare County Council offices “It takes the carpark surface water and filtrates it, then transfers it into storage tanks to be used as non-potable water in the building itself,” says Michael.

Now is the time to take notice of water management systems, according to the experts at Roadstone. “We have to look to the future, we have to put rain water management on a sustainable footing.” says Michael Vaughan. “We can’t keep putting water through existing systems because the capacity will keep increasing and increasing. We have to manage the possibility of flooding also, which happens throughout the country each year and this is one element that would help in managing it.”

The Roadstone Aquaflow paving system is ideal for new builds, and SuDS is something we will likely see as a requirement in new developments of the future, says Michael Vaughan.

“Roadstone are a one-stop shop for SuDS. Roadstone can provide a full design service for your Aquaflow paving system issuing a site specific Aquaflow design including construction depths, invert levels, restraints, drainage and any other design elements.”

Roadstone have shown full commitment to SuDS paving solutions by providing a SuDS equivalent for all their popular standard paving ranges. For example Roadstone Castlestone paving range has an Aquaflow Castlestone permeable paving equivalent. Permeable paving is available in a full range of colours including Roadstones popular blended colours. Other permeable finishes are available such as permeable porous asphalt in the form of the “Duraflow” product, permeable “no fines concrete” and “core gravel sheets” complete the permeable range.

CASE STUDY – ÁRAS CHILL DARA, SUSTAINABLE ENERGY IRELAND BUILDING OF THE YEAR 2006

  • Roadstone designed, Formpave Aquaflow system
  • 21,000m² car park
  • ML Aquaflow Paving Blocks and inbitex membrane in a 350mm deep sub-base (specification graded stone with 30% voids to maximize storage) over SC membrane to form a tanked system
  • Use of mains water reduced by incorporating filtered rainwater from the car park, which is stored to overhead storage tanks for non-potable water use.

12 YEARS ON

  • New adjacent 5,000m² asphalt carpark partially drains into the permeable paving and is accommodated by the existing system
  • Áras Chill Dara reported no standing water on the car-park even after major rain events, ensuring cleaner surfaces
  • Aquaflow ML Paving in good condition both visually and structurally
  • Today, the system is fully operational and providing water to overhead storage tanks for non-potable building services use as required

 

 

Interest grows in Roadstone SuDS systems – Construction Industry News

The following article first appeared in Construction Industry News and can be downloaded HERE

INTEREST GROWS IN ROADSTONE SuDS SYSTEMS AS DEVELOPERS LOOK FOR SURFACE WATER MANAGEMENT SOLUTIONS

Across the country water drainage and sewage systems handle the water runoff from large scale developments. As the scale of development increases in the coming years, the problem of surface water management will be greatly exacerbated.

According to Michael Vaughan, Roadstone National Sales Manager Architectural Products, an undeveloped site has a surface water run-off of 10%, while a high density development can experience a run-off of up to 55%.

The challenge of managing surface water run-off is being met by an increased use of SuDS (Sustainable Urban Drainage Systems) or permeable paving systems. One of the key principles of SuDS is reducing water quantity thus dealing with surface water at the source reduces the effects of urbanisation and the impact of localised flooding.

Michael says Roadstone has been receiving an increased number of enquiries from across the country in recent times about Roadstone’s Aquaflow (SuDS) range of paving.

Roadstone Aquaflow system allows rain to infiltrate through a permeable block paved surface into a unique sub-base before being released in a controlled manner into the ground or into main sewers or water courses. The system is capable of handling rainfall of 4500mm per sq. m per hour.

The water leaving the Aquaflow system is cleaned by filtration and microbial action and can also be stored in an integrated tanking system for secondary non-potable uses such as flushing toilets. watering soft landscapes and firefighting. A further advantage of Roadstone’s Aquaflow system is that roof water can be drained through an aquaflow distribution tank directly into the sub-base.

Roadstone can provide all the materials necessary to facilitate the design and construction of the Aquaflow  permeable paving system. Michael explains that the Roadstone team like to get involved in a project as early as possible so the project team can avail of their design and technical expertise.

In 2005, Roadstone designed the Formpave Aquaflow system to facilitate a 21,000-sq m car parking space at Aras Chill Dara, the then new Kildare County Council offices. Over the years,
Aras Chill Dara reported no standing water on the car-park, even after major rain events, ensuring cleaner surfaces. Twelve years on the Aquaflow Paving is still performing its water management function.

 

Developments in Roadstone’s Thermal Liteblock – Irish Building magazine

Part L, Liteblock

The following article first appeared in the Irish Building magazine and can be downloaded HERE

Award Winning Thermal Liteblock

Alan Lowe, Roadstone’s Senior Technical Manager discusses the new developments regarding Roadstone Thermal Liteblock, their large range of thermally modeled construction details and the features and benefits of the Thermal Liteblock which is available from Roadstone outlets nationwide.

Roadstone’s multi-award winning Thermal Liteblock is manufactured by Roadstone in Ireland. Thermal Liteblock is used at key junctions to provide reductions in thermal bridging and heat loss. It has thermal conductivity values less than 0.33 W/mK which is a 300% improvement over standard concrete blocks. This is achieved using a specific mix design which includes lightweight aggregates. This mix produces a robust concrete block with excellent insulation properties while maintaining structural strength and allowing for traditional construction methods to be used. Thermal Liteblock can be used with traditional mortars and renders and is compatible with standard concrete fixings.

By 2016 Thermal Liteblock was established in the market, winning national awards. Speaking to Irish building magazine, Alan says Thermal Liteblock has proved to be a very successful product, being specified by designers on a wide range of domestic, commercial and public projects. He describes Roadstone’s most recent addition to the Thermal Liteblock range, developing a higher strength Thermal Liteblock: “We have recently developed a 13N/mm² Thermal Liteblock. The building regulation minimum standard is 7.5 N/mm² for the compressive strength of standard and lightweight concrete blocks. The 13 N/mm² Thermal Liteblock is suitable where higher design strength is required, such as in commercial developments where compliance with NZEB (Near Zero-Energy Buildings) is required. Thermal Liteblock is now available in a range of strengths, sizes and configurations providing far greater design and construction flexibility for our customers.”

The Roadstone Thermal Liteblock system combines the Roadstone Thermal Liteblock with the Roadstone Concrete Block range, which when used in accordance with the Acceptable Construction Details (ACDs), achieves Psi values equal to or better than the standards set out in TGD Part L 2011. Roadstone have thermally modelled all relevant details in Appendix D of TGD L 2011. From this extensive research, Roadstone are now in a position to provide detail solutions that comply fully with Psi value requirements outlined in TGD L 2011 – Appendix D. Roadstone also offers a specialist design service. Alan explains, “If a client comes to us with a project at the design stage or with bespoke details we can engage our design consultants Evolusion Innovation to carry out fully certified y value calculations for the project. From this, we can assist our customers in identifying cost savings and/or enhanced Building Energy Rating (BER) performance. We have over 150 certified thermally modelled details that are available to our customers for incorporation into their projects.”

“We were able to achieve a thermally efficient block and one which meets the robustness, integrity and strength that is required by the Irish and European standards.”

Alan describes how the Thermal Liteblock was originally developed. “Roadstone recognised back in 2013 that Part L of the building regulations had changed the thermal bridging requirements for construction details. We reviewed the Psi value requirements in Part L and examined how we could achieve a more thermally efficient concrete block to achieve compliance. We completed 12 months of Research & Development to manufacture a concrete block with low density and improved thermal performance while maintaining the required structural characteristics of a concrete block.” Speaking of their success, he says, “We were able to achieve a thermally efficient block and one which meets the robustness, integrity and strength that is required by the Irish and European standards.”

Key features and benefits:

  • Reduced Thermal Bridging resulting in reduced heat loss, and lower heating bills.
  • Excellent thermal conductivity (Lambda λ) value less than 0.33 W/mK for masonry block.
  • Robust and durable concrete block with a minimum compressive strength of 7.5N/mm².
  • Suits traditional construction methods familiar to Irish and UK designers and builders.
  • CE marked – manufactured to the requirements of I.S. EN 771-3 to System 2+.
  • Thermal Liteblock is required only in key locations in conjunction with the Roadstone Concrete Block range.
  • The Roadstone Thermal Liteblock system is a very cost effective solution and can result in significant savings in the overall build cost.
  • Improved (y) value calculations are achieved when using the Roadstone Thermal Liteblock system.
  • When a full building specific (y) value calculation is carried out using the Psi Values incorporating the Roadstone Thermal Liteblock, improved (y) value of between 0.03 and 0.06 can typically be achieved.
  • Compliant U-values are achieved without having to provide a cavity in excess of 150mm.
  • Roadstone Thermal Liteblock is unique in colour to enable traceability on site.
  • Photographic recording of the Thermal Liteblock built on site can then form evidence of compliance for the Assigned Certifier, Architects, Engineers and BER assessors.
