Accelerating admixtures - Concrete

Accelerating admixtures can be used to increase either the rate of stiffening or setting of the concrete or the rate of hardening and early strength gain to allow earlier formwork striking and demoulding. Most accelerators achieve one rather than both of these functions. Hardening accelerators are most effective at low temperature. Accelerators can be used with superplasticisers where early ...
