Is there any method being used to test the compressive strength of the concrete without destructing?  Yes, there is. The Rebound hammer test (Non-destructive test) is widely used to determine the compressive strength of the concrete elements, also called as Schmidt hammer test.  We have already discussed some of the…

Have you seen wet clay soil where the water evaporates quickly and then makes the soil surface look like below? What is shrinkage in concrete? Like in the clay soil, concrete also changes in volume after evaporation of water and makes cracks. The process of volumetric change in concrete due…
