摘　　要：将稻壳掺入渠道衬砌混凝土中,一方面利用了农业废料,另一方面使衬砌材料具有防渗和保温防冻胀的双重功能。研究了稻壳的粒径和水灰比对稻壳混凝土抗压强度的影响规律。试验结果表明,稻壳混凝土的抗压强度随着稻壳粒径的增大呈现出先增大后减小的变化规律;随着水灰比的增大混凝土的抗压强度不断减小;稻壳混凝土强度的影响因素,从大到小依次为水灰比、稻壳粒径以及水灰比和稻壳粒径的交互作用。Mixing rice husk into concrete has 2 advantages,agricultural waste is utilized and it makes the concrete lining materials have the properties of anti-seepage and anti-frost.We conduct a research about the effects of rice husk particle size and water-cement ratio on the compressive strength of the rice husk concrete.The results show that,with the increase of rice husk particle size,concrete compressive strength increases first and then decreases;with the increase of water-cement ratio,the compressive strength of concrete decreases constantly.The sequence of factors affecting concrete strength are：water-cement ratio,rice husk particle size and the interaction of water-cement ratio and the rice husk particle size.
