The invention discloses water-permeable concrete and a preparation method thereof. The water-permeable concrete is prepared from the following components in parts by weight: 120-160 parts of cement, 80-120 parts of superfine slag powder, 100-120 parts of secondary fly ash, 40-60 parts of a water reducing agent, 180-220 parts of slurry and 120-140 parts of water. According to the water-permeable concrete and the preparation method thereof, by adopting the polycarboxylate superplasticizer, the water-binder ratio can be effectively reduced, the water permeability requirement of the concrete is ensured, and the water-permeable effect of the concrete is improved by adding the superfine slag powder and the secondary fly ash into the raw materials; concrete production raw materials in a materialstorage box are lifted to the top of a material lifting shell through a material lifting packing auger arranged on the surface of a material lifting roller, and enter a stirring tank through a material guide pipe, and liquid raw materials are introduced into the stirring tank through a liquid inlet pipe; the harm of flying dust generated in the concrete production process to the body health of carrying personnel can be greatly reduced, and the body health of workers is protected to the maximum extent.
本发明公开了一种透水型混凝土及其制备方法，透水型混凝土由水泥120‑160份、矿渣微粉80‑120份、二级粉煤灰100‑120份、减水剂40‑60份、浆水180‑220份和水120‑140份组成。该透水型混凝土及其制备方法，通过采用聚羧酸减水剂，可以有效降低水胶比，保证混凝土的透水性要求，在原料中添加矿渣微粉和二级粉煤灰提高混凝土的透水效果，利用提料滚筒表面设置的提料绞龙对存料箱中的混凝土生产原料向提料壳体的顶部提升，原料通过导料管进入到搅拌罐的内部，通过进液管向搅拌罐的内部通入液体原料，可以大幅降低混凝土在生产过程中产生的扬尘对搬运人员身体健康造成危害，最大限度地保护了工作人员的身体健康。
