生态型透水混凝土配合比设计及性能研究
|
摘要
该文在现有理论及实验基础上,引入生态型透水混凝土的概念。采用正交试验法进行生态型透水混凝土的试验配合比设计,选用四因素三水平正交表,分别研究了目标孔隙率、水灰比、硅灰掺量、粉煤灰掺量四个因素的三种变化水平。在总胶凝材料为450 kg/m~3,胶粉掺量为1%时(其中硅灰掺量7.5%、粉煤灰掺量10%),水灰比控制为0.28,制备的透水混凝土具有较好的抗压强度和一定的透水能力(孔隙率可达15%左右)。
This paper introduced the concept of ecological permeable concrete based on existing theory and experiment.The experimental mix design of ecological permeable concrete was carried out by orthogonal test method.The four factors and three levels orthogonal table were used to study the target porosity,water-cement ratio,silica fume content and fly ash blending,with three levels of changing in the four factors.When the total cementing material is 450 kg/m~3 and the rubber powder is 1%(The content of silica ash is 7.5%,and the content of fly ash is 10%),The water-cement ratio is 0.28,and the prepared permeable concrete has a certain water permeability and good water permeability(Porosity up to about 15%).
