Accelerators speed up the hydration (hardening) in the concrete. Normal supplies utilised are calcium chloride, calcium nitrate and sodium nitrate. Having said that, usage of chlorides may result in corrosion in steel reinforcing which is prohibited in a few countries, to ensure that nitrates could possibly be favored, Regardless that they are much less successful in comparison to the chloride salt.
