First of all let us understand what an accelerator is. An accelerator is a chemical admixture which increases the rate of hydration of concrete; which results in rapid gain of strength in concrete. Some of the examples of accelerators are- Calcium chloride, Flourosilicates, silicates, tri-ethanol amine etc. The mechanism it follows is that the admixture combines with C3A and form hydrocomplex compounds which activates C3A and increases the rate of hydration.
