Cement Admixture - an overview | ScienceDirect Topics

The results show that using a fine fly ash as a supplementary cement admixture has no effect on the freeze–thaw resistance of ed concrete. Moreover, while the mixes with a dry density of 1000 kg/m 3 showed more expansion during the test than those with a density of 1400 kg/m 3, they also exhibited more compressive strength at the end.
