摘 要:采用黏度作为聚合物掺量衡量标准,制作了5组不同聚合物透水混凝土试件,通过测定其抗压强度、抗折强度、透水系数分析了不同聚合物对透水混凝土性能的影响。试验结果表明:羟丙基甲基纤维素可明显提升透水混凝土的透水性能,可再分散乳胶粉可明显地提高透水混凝土的抗压强度,出现抗压强度和透水性“效果互补”现象。
Abstract: Viscosity is used as the standard for measuring the content of polyme,and five groups of different polymer pervious concrete specimens are made. The compression strength, rupture strength and permeability coefficient of the polymer pervious concrete specimens are tested to study the influence of different polymers on these properties. The results show that the hydroxypropyl methyl cellulose can significantly improve the permeability of pervious concrete, the redispersible polymer powder can also obviously improve the compression strength of the permeable concrete, thus the "effect complementary" phenomenon of compression strength and water permeability is shown.
