Abstract: The effects of different content of granite stone powder on workability, compressive strength, early age shrinkage deformation and resistance to chloride ion penetration of C25, C45 and C60 concrete machine-made sand were discussed. The experimental results demonstrated that the reasonable content scope of stone powder was respectively 11~14% for low-strength concrete(C25) and mid-strength concrete(C45) and 6%~9% for high-strength concrete(C60). Those reasonable scopes obtained in our researches have greatly exceeded the specified values respectively of not more than 10% for MB≤1.4 and 1%~5% for MB>1.4 machine-made sand formulated by the existing Chinese Standard of GB14684-2011.
