Simple concrete will not easily withstand tensile and shear stresses due to wind, earthquakes, vibrations, along with other forces and it is as a result unsuitable in many structural programs.
Accelerators speed up the hydration (hardening) with the concrete. Typical components used are calcium chloride, calcium nitrate and sodium nitrate. However, utilization of chlorides may well trigger corrosion in steel reinforcing which is prohibited in some nations, to ensure that nitrates could possibly be favored, Although They can be significantly less productive when compared to the chloride salt.
