Rapid permeable compressive concrete
The invention provides rapid permeable compressive concrete and a preparation method thereof. The permeable concrete is prepared into two layers, more stones with small particle sizes are contained in the permeable concrete on the surface layer, more stones with large particle sizes are contained in the permeable concrete on the bottom layer, and rainwater can be filtered and permeated through the special structure. A binder is added to increase the cohesiveness between the framework to improve the compressive strength, meanwhile, the concrete has the effect of a water reducing agent, and sodium nitrate, ammonium nitrite, ethylene glycol and other components have the effect of reducing the freezing point, so that the anti-freezing capacity of the concrete is improved. Modified steel fibers are added to support the concrete, so that the compressive strength of the concrete is improved. A water repellent agent is added into the permeable concrete, so that the contact time and area with water are reduced, water is quickly drained, water in the concrete is reduced, and the compressive strength and water permeability of the concrete are protected.
本发明提供了一种快速透水抗压混凝土及其制备方法。其中透水混凝土制备成两层，表层透水混凝土中粒径小的石子较多，底层透水混凝土中粒径大的石子较多，特殊的结构同时可对雨水进行过滤渗透。添加粘结剂，增加骨架间粘结性来提高抗压强度，同时具有减水剂的功效，其中硝酸钠、亚硝酸铵以及乙二醇等成分具有降低冰点的功效，提高混凝土的抗冻能力。加入改性钢纤维来支撑混凝土，提高混凝土的抗压强度。在透水砼中增加疏水剂，减少与水分接触的时间和面积，快速排水，减少混凝土内部存在的水分，保护混凝土的抗压强度和透水性能。
