低胶凝材料用量透水混凝土的抗堵塞性研究
摘要
Abstract
In order to reduce the energy consumption in the production and use of pervious concrete and extend the service life of pervious concrete,the water permeability and clogging resistance properties of pervious concrete with low cementitious material content were studied by controlling the particle size and uniform slurry distribution.The research results show that:Reducing the amount of cementitious material can improve the uniformity of slurry distribution in pervious concrete and reduce the difference in pore structures between the top and bottom surfaces;the initial water permeability coefficient of pervious concrete with low cementitious material content can reach 20 mm/s,and it has good resistance to sediment with a particle size of 0～0.6 mm;the settlement of slurry will lead to a reduction in the initial water permeability coefficient and clogging resistance property of pervious concrete;When the porosity is similar,reducing the aggregate particle size will slightly reduce the initial water permeability and greatly weaken the plugging resistance.关键词
