Frost Durability and Strength of Concrete Prepared with Crushed Sand of Different Characteristics by Ming-kai Zhou, Zhan-ao Liu, Xiao Chen

“…Lithology has no prominent influence on frost durability and compressive strength of CSC within the lithologies (dolomite, limestone, granite, basalt, and quartz) studied. Though compressive strength of CSC is a little higher than RSC under equal water to cement ratio, frost durability of CSC is no better than RSC especially for C30 CSC, and air-entraining agent is suggested for enhancing frost durability of C30 CSC exposed to freezing environment.…”
