摘　　要：为促进活性粉末混凝土在工程中的应用,收集整理与活性粉末混凝土相关的文献.提出以边长70.7 mm立方体抗压强度标准值为依据的活性粉末混凝土强度等级划分方法.对活性粉末混凝土立方体抗压强度尺寸效应、轴心抗压强度、轴心抗拉强度、弹性模量、峰值压应变和极限压应变等基本力学性能指标进行分析,获得了活性粉末混凝土相关力学性能指标之间的换算关系,并基于一次二阶矩法推导得出活性粉末混凝土的材料分项系数.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.
