Working in extreme cold or extreme heat? Temperature differentials between the concrete and the ambient environment can have very negative impacts on the concrete strength and quality.
Building in winter?
At temperatures below 10°C, concrete strength takes a longer curing period to achieve. For example, concrete cured at 10°C takes twice as long to achieve compressive strength as concrete cured at 22°C. By maintaining curing temperatures in cold weather, quality and strength of concrete can be achieved more quickly.
A related symptom caused by low temperatures is ‘thermal fatigue’, where the disparity between the surface and the core of the slab contributes to cracking during curing.
Building in summer?
Concrete curing in high ambient temperatures (above 32°C) is at risk of uneven and defective hydration. This in turn potentially results in excessive cracking, and long-term durability issues.
What is the solution?
Many methods of insulating the curing concrete are time-consuming and difficult.
Markham offers CONQOR TCB, the effective and easy to use solution to maintaining curing temperatures in concrete. This lightweight cover is easy to install, can be re-used, and is also available in custom shapes or sizes.
- Protect against low or high temperatures
- Durability enhanced – allows the concrete to achieve desired strength in a shorter time frame.
- CONQOR TCB will protect the concrete while curing and CONQOR TCB reduces the temperature differential between the core and surface curing temperatures.
- CONQOR TCB also assists in reducing shrinkage.
