Effect of supplementary cementitious materials on the resistance of cement paste to carbonic acid water
Cement pastes blended with fly ash or slag suffering from carbonic acid water were investigated. Thermogravimetric analysis was performed to determine the effect of fly ash and slag on CH content in cement pastes. Mercury intrusion porosimetry was used to characterize the effect of fly ash and slag...
