Properties of concrete

Concrete tests can measure the "plastic" (unhydrated) properties of concrete prior to, and during placement As these properties affect the hardened compressive strength and durability of concrete (resistance to freeze-thaw), the properties of workability (slump/flow), temperature, density and age are monitored to ensure the production and ....

Strength development in concrete

Concrete strength Many factors influence the rate at which the strength of concrete increases after mixing Some of these are discussed below First, though a couple of definitions will be useful: The processes of 'setting' and 'hardening' are often confused: Setting is the stiffening of the concrete after it has been placed A concrete can be ,...
