Incorporating CES Quarry Products Ltd fleet of RMC & Mini-Mix lorries, working from early morning, six days a week.
CES Quarry Products Ltd provide a superior ready mixed concrete service enabling us to deliver a payload as little as a 0.3 of a metre in one of our Mini Mix Lorries or up to a 1000 metres daily with a fleet of our full size ready mixed concrete lorries.
All external concrete exposed to the freeze thaw cycle should be air entrained
Winter warning.
In comparison to some other concrete suppliers CES have experienced very little frost damage to our ready mix concrete supplied over the winter period.
We believe the main reasons are:
- Our concrete is produced to EN 206-1 meaning amongst many things that our cement contents and 28 days strengths are higher than some of the competition. Typically our 35n concrete at 28 days will achieve over 40n. Sample results are readily available upon request.
- Most of our slumped concrete contains a percentage of crushed rock fines. This product speeds the initial setting time and minimises bleed helping the surface to retain its integrity.
- Using top qualtity aggregates, mainly gritstone minimising the chance of pop outs.
- Using top qualtity WRAs, helping to reduce the water content needed to achieve workability.
Below is some information that may help you when considering the durability of concrete and minimising the potential for frost damage.
Frost proofer as its called is often used by us upon request but is actually an accelerator and not anti- freeze and is only effective during the initial curing period giving no long term protection.
The theory being that by accelerating the initial setting time the concrete generates its own heat and cures before the frost gets its way, although a heavy and persistant frost may over come these benefits.
Unlike frost proofer air entrainer does give long term protection against frost damage.
Air entrained concrete contains billions of microscopic air cells per cubic metre. These air pockets relieve internal pressure on the concrete by providing tiny chambers for water to expand into when it freezes.
Air entrained concrete is not as effective when power floated as this process can burst the air cells but is perfect for tampered areas.
Air entrained concrete considerably increases the durability of the surface which is exposed to the freeze thaw cycle and other damaging salts.
Unfortunately Air entrained concrete needs a higher cement content to compensate for the air cells causing some added expense.
Unfortunately Air entrained concrete gives no protection against frost during the initial setting time.
