However, air-entrained alkali-activated slag concrete suffered more damage than Portland cement concrete during the freeze-thaw tests. Pu et al. (1988) (cited by Wang et al., 1995 ) studied the frost resistance of AAS concretes having different strengths (low, medium and high) according to a Chinese standard in which the freezing took place in air.

Properties of Hardened Concrete with Blast Furnace Slag

By and large, compressive strength of slag concrete gradually increases from 1-5 days and lower than that of concrete without slag, but slag concrete strength matches strength of controlled concrete from 7-28 days. Moreover, slag concrete compressive strength surpasses strength of concrete with zero slag after 28 days.
