Accelerators speed up the hydration (hardening) of your concrete. Normal components utilized are calcium chloride, calcium nitrate and sodium nitrate. Nonetheless, usage of chlorides might induce corrosion in steel reinforcing and is particularly prohibited in some nations around the world, in order that nitrates can be favored, Despite the fact that They are really considerably less efficient in comparison to the chloride salt.
