Concrete cracks are common and develop when stresses in the concrete exceed its strength. Cracks are often caused by normal shrinkage of the concrete when hardening and drying.
Why Is My Concrete Cracking?
Cracking in concrete is a common problem, but it can be alarming when it happens. It’s important to understand why concrete cracks so that you can take the necessary steps to prevent it in the future. This article will explain why concrete cracks and the measures you can take to prevent it.
One of the main reasons why concrete cracks is due to temperature changes. Concrete is an extremely porous material, and when temperatures fluctuate, the concrete will expand and contract. This can cause cracks to form in the concrete as it cannot accommodate the temperature changes.
Another cause of concrete cracking is improper curing. Concrete needs to be adequately cured in order to prevent cracking. This involves ensuring the concrete is kept moist and not exposed to sunlight, wind, or other extreme weather conditions. If the concrete is not cured correctly, it can become weakened and prone to cracking.
The type of aggregate used in the concrete can also affect its propensity to crack. Sums that are too large can cause the concrete to crack due to the lack of air pockets that can accommodate the expansion and contraction caused by temperature changes. The concrete will not be as prone to cracking if smaller aggregates are used.
