【摘要】 为配制达到一定指标的透水砼,研究了不同的搅拌方式和成型工艺对透水砼性能的影响。经对比试验的结果表明:在一定配合比下,搅拌方式采用一次性投料,成型方式采用振动成型,即能满足透水砼透水性能K15>1mm/s,及强度指标28 d抗压强度>25 MPa的要求。更多还原

【Abstract】 Porous concrete properties were studied with the experiments of two mixing methods and different formation ways to prepare a porous concrete with certain target.With certain proportion,the porous concrete targets of permeability coefficient(K15>1 mm/s) and compressive strength(R28>25 MPa) can be obtained by using one-time mixing material and vibrating compaction.更多还原
