Summary: Tests on concrete in strength and durability aspects are explained in detail. Initial setting time of cement and concrete are measured in different apparatus. How do we measure workability for very stiff, normal and flowing concrete? Explanations about stress-strain graph of concrete, modulus of elasticity of concrete, compression, tensile strength of concrete are really awesome.
