Calcium Chloride On Concrete

The accelerated cure rate measured as final concrete set time can be reduced by two thirds when two per cent calcium chloride is added two hours compared to six hours for plain concrete morris chemicals s e r t s calcium chloride can accelerate cement hydration reducing its set time.

Calcium chloride on concrete.
