Low-binder pervious concrete

The invention provides low-binder pervious concrete and belongs to the field of concrete. By using alkali mud and citric acid residue as a substitute binder, the production cost of previous concrete can be decreased, and the environmental pollution problem due to alkali mud and citric acid residue can be solved. The low-binder pervious concrete is made with, by weight, 180-220 parts of cement, 40-60 parts of alkali mud, 30-50 parts of citric acid residue, 80-100 parts of water, 1420-1470 parts of crushed stone, 5-6.6 parts of coarse salt, and 2.75-3.63 parts of a superplasticizer. 本发明提出种低胶材透水混凝土，属于混凝土领域，利用碱泥和柠檬酸渣作为代胶材，不仅能够降低透水混凝土的生产成本，而且解决了碱泥和柠檬酸渣对环境的污染问题。该低胶材透水混凝土包括水泥、碱泥、柠檬酸渣、水、石子、粗盐、高性能减水剂；按重量份数计，各组分配比为：水泥180-220份，碱泥40-60份，柠檬酸渣30-50份，水80-100份，石子1420-1470份，粗盐5-6.6份，高性能减水剂2.75-3.63份。
