摘　　要：利用农业生产的废弃物——稻壳为骨料制备混凝土,研究了不同稻壳掺量混凝土的表观密度和抗压强度。结果表明:随着稻壳掺量的增大,混凝土表观密度和抗压强度逐渐降低。稻壳掺量达到13%后,其减小的速度明显放缓;稻壳混凝土抗压强度随水灰比增大而降低的幅度明显小于普通混凝土。The rice husk,a kind ofargricultural waste,is used as materials in the production of concrete to investigate the apparent density and the compressive strength of concrete with different rice husk amount.The results show that the compressive strength and apparent density of concrete gradually decreased with the increasing office husk amount.It obvious slows down in the rate decrease when rice husk amount reached 13% ;the decrease rate of rice husk concrete compressive strength is smaller than ordinary concrete with the water-cement ratio increase.
