Basic mechanical property indexes of reactive powder concrete

To promote engineering application of reactive powder concrete, relative research literatures published are summarized and studied. The method of classifying strength grade of reactive powder concrete is proposed according to characteristic value of 70.7 mm side length cube compressive strength. Reactive powder concrete mechanical property indexes on size effect of compressive strength, axial compressive strength, axial tensile strength, elastic modulus, peek compressive strain and ultimate compressive strain are analyzed, and the conversion relation of these mechanical property indexes are obtained. The material partial factor of reactive powder concrete is calculated based on first-order second-moment theory.
