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 may 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 'set' in that it is no longer fluid but it may
