Properties of hardened concrete - Civil Engineering Realities

2020-7-17  Concrete is subjected to either autogenous or induced volume changes. Volume change is one of the most damaging properties of concrete, affecting long-term strength and durability. For the practical engineer, the aspect of volume change in concrete is important from the point of view that it produces unsightly cracks in the concrete.

Fresh concrete and its properties?

2020-7-8  The hardening of concrete before its hydration is known as setting of concrete. OR The hardening of concrete before it gains strength. OR The transition process of changing of concrete from plastic state to hardened state. Setting of concrete is based or related to the setting of cement paste. Thus cement properties greatly affect the setting time.
