Hardened Concrete: Properties of Hardened Concrete

Properties of hardened concrete: 1. Strength: The strength of concrete is defined as the maximum stress it can withstand or the maximum it can yield. Cubes, cylinders and prisms are 3 types of compression test specimens. Flexible tensile tests are used to estimate the load at which concrete members can crack, while compressive strength is taken ...
