Experimental Research on Compressive Strength and Storage Period for Dry-Mixed Material of Shotcrete

Abstract:

According to dry-mixed materials of shotcrete which composed of raw materials in mix proportion the concrete quality as field mixing were included. Through the experimental research on the storage period of using dry-mixed materials in shotcrete, variations of compressive strength were obtained. In according with the studies on the storage period of dry-mixed materials in 7d, 11d, 15d, 20d and 28d, compared with 0d, the loss of compressive strength were obtained under different sand water content (0%, 0.5% and 1.0%). The results shown that strength loss rate of C30 concrete was 6.7% when the sand water content was 0.5% in the 28d and while strength loss rate was 12.0% when the sand water content was 1.0%. The studies on storage period provide supports to the using of dry-mixed shotcrete in engineering application.
