Experiment Test on Expanding Agent Affected to Mechanics Performances of Fly Ash Shotcrete
Abstract：Under the certain accelerating agent mixed, a study was conducted on the mechanics performanees of the shotcrete under the effect of the different quantity fly ash and swelling agent mixed. The study results showed that when the mixed value of the swelling agent was 6%, the shrinking compensated shotcrete with a single swelling agent mixed would have good compressive and splitting tensile strength performances. As for the shot fly ash concrete with single fly ash mixed, the compressive and splitting tensile strength would be reduced with the fly ash mixed value increased. When the swelling agent mixed value was 6% and the fly ash mixed value was 10% , the effect of the shot shrinking compensated fly ash concrete will be the best and the compressive and splitting tensile strength would be in- creased with 4. 5% and 6.6% higher than the plain concrete individually.
