摘要
试验研究了聚合物的不同掺量对透水性混凝土的强度和透水性能的影响。结果表明,聚合物的加入,可有效改善透水性混凝土的新拌性能,显著提高透水性混凝土的抗折强度和抗压强度,但对透水系数的影响较小。从经济和技术两方面考虑,聚合物在透水性混凝土中的适宜掺量在15%￣20%之间。
The influence of different contents of polymer onto strength and water permeability of porous concrete are experimentally stadied. The results show that by addition of polymer the workability of concrete is improved and the flexural strength and the compressive strength of porous concrete are increased obviously. But, for the permeability coefficient there is very little influence. Considered from economy and technique, the best content of polymer in porous concrete is between 15% and 20% of cement mass,
