Cement, Quick-Setting

Cement, Quick-Setting

 

cement characterized by a rapid increase in strength during the initial hardening period. It is used chiefly in fabricating precast reinforced-concrete structural members and items. The enhanced mechanical strength of quick-setting cement during the early hardening period is due to the specific mineralogical composition and the microstructure of the clinker, the proportioning of additives, and the fineness to which the cement is ground.

The types produced include quick-setting portland cement with compressive strength after three days of 25 meganewtons per sq m (250 kilograms-force per sq cm), particularly quick-setting portland cement, and also quick-setting slag-portland cement.
