無砂透水混凝土配合比設(shè)計摘要:無砂透水混凝土具有多孔、透水性好、有一定的強度,在鐵路的隧道、橋涵臺背等部位作為排水或反濾結(jié)構(gòu)。本文對無砂透水混凝土的配比設(shè)計進行了試驗,分析影響無砂透水混凝土強度及滲透系數(shù)的因數(shù)。關(guān)鍵詞:無砂透水混凝土。 配合比。 滲透系數(shù)。 水灰比;孔隙率abstract: no sand permeable concrete with porous and permeability, be of strength in the rail tunnel, which sets back the drainage or inverted filter parts as structure. in this paper the water concrete without sand ratio design test, no sand permeable analysis on strength of concrete and the coefficient of permeability factor.key words: no sand permeable concrete。 mix。
