稻壳掺量及粒径对混凝土抗压强度影响的试验研究

对稻壳浸泡除糖,试验研究其掺量和粒径对C40混凝土抗压强度的影响规律.结果表明：混凝土中添加稻壳粉后混凝土抗压强度明显降低,且混凝土抗压强度的降低随稻壳掺量的增加大致呈线性变化规律;稻壳粒径大小对混凝土抗压强度有影响,表现为先增大后减小的趋势.稻壳掺量3%,粒径3.15 mm时可制备出C30混凝土.

Experiment on Effects of Rice Husk Quantity and Particle Size on the Compressive Strength of Concrete

The effects of rice husk quantity and particle size on concrete compressive strength of C40 are studied by soaking rice husk to remove the sugar. The result shows concrete compressive strength reduces significantly,and the decrease of law concrete compressive strength is roughly linear with the content of rice husk increasing;The rice husk particle size affects on the compressive strength of concrete,the law of the effect increases at the first and then decreases;C30 concrete can be prepared if the rice husk content is 3% and the particle size of rice husk is 3. 15 mm.
