Investigation of resistance of preplaced-aggregate concrete to freezing and thawing
Resistance of conventional preplaced-aggregate concrete at age of 28 days to accelerated freezing and thawing is much less than that of concrete containing air-entraining admixture (AEA) both conventionally mixed and replaced; results of tests of preplaced-aggregate concrete containing AEA for resistance to freezing and thawing were approximately same as concrete conventionally mixed containing AEA; addition of AEA increases these values regardless of delay time between mixing and pumping of grout.
