The invention discloses a method for preparing C20 pervious concrete by using recycled stone. The C20 pervious concrete is prepared from the following raw materials: water, cement, a reinforcing agent, pottery sand, the recycled stone and a water reducing agent in a ratio of 130: 300: 20: 100: 1550: 2, the preparation method of the C20 pervious concrete comprises the following steps: putting pottery sand, regenerated stone and 50% of mixing water into a concrete mixer, and stirring for 30 seconds; adding the cement and the reinforcing agent, and stirring for 60 seconds; adding the rest 50% of water for mixing, stirring for 60 seconds, and discharging; when the C20 pervious concrete is formed, vibrating is conducted in an inserting and tamping forming mode; and finally, a ZB5 flat plate vibration troweling machine is used for troweling the surface for 30 s, and a pervious concrete blank is obtained. A certain proportion of super glue is added into the raw materials, the bonding degree between the raw materials is guaranteed, meanwhile, a certain proportion of pottery sand is added to replace a part of pebbles, the weight is reduced, and then the effects of light weight and high strength are achieved.
本发明公开了一种利用再生石制备C20透水混凝土的方法，所述C20透水混凝土原料配比为：水：水泥：增强剂：陶砂：再生石：减水剂=130:300：20：100:1550:2；所述C20透水混凝土包括如下制备步骤：混凝土搅拌机中投入陶砂和再生石与50%拌合用水，搅拌30s；之后投入水泥和增强剂，搅拌60s；之后投入剩余的50%拌合用水，搅拌60s，出料；C20透水混凝土成型时，采用插捣成型方式进行振捣；最后用ZB5平板振动抹光机将表面抹平，时长30s，得到透水混凝土坯体。该发明在原料中添加一定比例强力胶，保证原料之间的粘结度，同时在其中加入一定比例的陶砂代替一部分石子，降低重量，进而达到轻质高强的效果。
