EFFECT OF CEMENT TYPE AND EXPANSIVE ADDITIVE ON RESISTANCE TO CRACKING OF LOW-CARBON CONCRETE USING FLY ASH AND GROUND GRANULATED BLAST-FURNACE SLAG

Abstract eng:
In this paper, effect of cement type and expansive additive content on resistance to both drying shrinkage cracking and thermal cracking of concrete using fly ash and ground granulated blast-furnace slag was investigated by experiments and thermal stress analyses. Days of cracking occurrence in test for drying shrinkage cracking of restricted concrete were able to be prolonged apparently with relative lower expansive additive content regardless of the cement type, and the resistance to drying shrinkage cracking was enhanced. Also, the resistance to thermal cracking was improved greatly by using low heat type cement and expansive additive.
