摘　　要：研究了稻壳灰作为一种添加剂,0～30%的等量取代水泥后,对混凝土性能的影响。混凝土的配合比为1:2:4:0.6(水泥:砂:碎石:水胶比)。测试了稻壳灰混凝土试件性质、抗压强度、劈裂抗拉强度、抗折强度等。结果表明,随着稻壳灰用量的增加,混凝土凝结的时间延长,而抗压强度、劈裂抗拉强度、抗折强度相应的降低。An innovative use office hull ash （RHS） as a filler in concrete is discussed.RHS in the range of 0-30% was used as a partial replacement for ordinary cement in a concrete of mix ratio 1 ： 2： 4： 0.6 （cement： sand： coarse aggregate： water cement ratio）.Fresh concrete properties, compressive-strength, split tensile strength, and modulus of rupture were measured for concrete mixtures with RHS within the investigated replacement levels.The results show that the setting times of RSH concrete increased with higher ash content, while the compressive strength, split tensile strength and modulus of rupture showed a reverse trend.
