| 摘 要： | 以稻壳、粉煤灰、硅灰及水泥等为原料,用全计算配合比法配制稻壳混凝土,试验研究C30稻壳混凝土性能.结果表明:合理的稻壳掺量对混凝土的工作性能有一定的改善作用;适量掺入粉煤灰可以润滑集料颗粒,使混凝土具有更好的黏聚性和可塑性;硅灰和粉煤灰双掺,可以改善稻壳混凝土的黏聚性和保水性,比单掺粉煤灰效果更好.

| Abstract: | The performance of rice husk concrete ( RHC) of C30 was researched,taking rice husk,fly ash,silica fume and cement as main materials,the mixed ratio of RHC is prepared by using the overall calculation method. The results showed that:The reasonable rice husk content can improve the workability of concrete. Reasonable fly ash content lubricates aggregate particles,and increases cohesiveness and plasticity of concrete. Dual-doped silica fume and fly ash can improve the cohesiveness and water retention of rice husk concrete,which is better than the case of single-doped fly ash. |
