Pervious concrete admixture and pervious concrete pavement containing same
The invention provides a pervious concrete admixture. The pervious concrete admixture is prepared from the following components in percentage by weight: 5 to 8 weight percent of boric acid, 3 to 9 weight percent of sodium fluosilicate, 12 to 15 weight percent of magnesium chloride, 2 to 8 weight percent of sodium hexametaphosphate, 2 to 4 weight percent of silicon nitride powder, 4 to 10 weight percent of potassium chloride, 10 to 12 weight percent of calcium chloride, 0.1 to 0.2 weight percent of chelating dispersant, 0.05 to 0.09 weight percent of sodium gluconate and the balance of water. The pervious concrete and the pervious concrete pavement prepared by adopting the pervious concrete admixture disclosed by the invention have excellent mechanical properties, durability and low-temperature pervious performance, and the defects of low strength and poor frost resistance of the pervious concrete can be overcome.
本发明提供一种透水混凝土外加剂，其包括以下组分按下述重量分数比组成：5～8wt％的硼酸，3～9wt％的氟硅酸钠，12～15wt％的氯化镁，2～8wt％的六偏磷酸钠，2～4wt％的氮化硅粉，4～10wt％的氯化钾，10～12wt％的氯化钙，0.1～0.2wt％的螯合分散剂，0.05～0.09wt％的葡萄糖酸钠，和余量的水。采用本申请公开的透水混凝土外加剂制备的透水混凝土及透水混凝土路面，具备优异的力学性能、耐久性能和低温透水性能，能够解决透水混凝土强度低和抗冻性能差的缺陷。
