Abstract

The invention belongs to the technical field of building materials, and in particular relates to a water-permeable foam concrete. The permeable foam concrete is made of the following raw materials in parts by weight: 160-420 parts of cement, 0.2-0.4 parts of foaming agent, 2-5 parts of water reducing agent, 1-5 parts of expanding agent, and 1-5 parts of plasticizer 5 parts and 90‑150 parts water. The foaming agent is made of the following raw materials in parts by weight: 200-260 parts of foaming agent, 20-30 parts of foam stabilizer, 3-8 parts of flocculant, 1-2 parts of thickener, 1.5 parts of preservative ‑2.5 parts and water 420‑480 parts. The water-permeable foam concrete of the present invention has a loose structure, does not feel greasy, has a good effect of connecting holes, has high water-permeable characteristics, and has high compressive strength at the same time, thereby improving the durability of the product.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a water-permeable foam concrete. Background technique [0002] With the development of the city, after the heavy rain on the urban road surface, there is a great pressure on the water supply and drainage, and the landscape of the urban ocean often appears. The main reason is that the urban municipal pipe network is becoming more and more complicated, the drainage is not timely enough, and the drainage effect is also poor. In recent years, foamed concrete has become more and more popular in urban water supply and drainage. Foamed concrete is made by mechanically foaming the foaming agent through the foaming system of the foaming machine, and uniformly mixing the foam with cement slurry, and then foaming The pumping system of the machine is used for cast-in-place construction or mold forming. After natural curing, it is a new type of lightweight thermal insul...
