摘要
通过室内试验和结果对比分析,研究细料、减水剂、硅灰和聚合物对多孔水泥混凝土强度的影响。结果表明,加入细料提高了多孔水泥混凝土强度,同时也大幅度降低了连通空隙率;减水剂能减小水灰比,提高多孔水泥混凝土的抗压强度;硅粉对多孔水泥混凝土的抗压强度提高比较明显;聚合物对多孔水泥混凝土的抗折强度提高比较明显。
Laboratory experiments and comparative methods were used to study the effects of fine material,water reducing admixture,silica fume and polymer latex on the strength of porous cement concrete.The results indicate that the addition of fine material improves the strength of porous cement concrete,but also reduces the connected porosity greatly.Water reducing admixture can reduce the ratio of water cement and improve the strength of porous cement concrete.Silica fume can improve compressive strength of porous cement concrete obviously and polymer can improve flexural strength obviously.
