Abstract

The invention discloses a sponge water-permeable brick and a preparation method thereof, and belongs to the technical field of a water-permeable brick. The sponge water-permeable brick is prepared from the following raw materials in parts by weight: 80 to 90 parts of sludge powder, 5 to 10 parts of modified polypropylene fiber, 3 to 5 parts of granite aggregate, 1 to 3 parts of expanded perlite, 15 to 20 parts of bentonite, 5 to 10 parts of coal ash and 5 to 10 parts of diatomite. The water-permeable brick prepared by the method has high compressive strength and high water permeability, has sound absorbing and noise reducing properties, accords with the industrial standard of Water-permeable Brick (CJ/T945-2005), is low in cost, can perform industrial production, responds to sponge city concept and can serve as an important building material in sponge city construction.

Description

technical field [0001] The invention relates to the technical field of permeable bricks, in particular to a sponge permeable brick and a preparation method thereof. Background technique [0002] In today's era of comprehensive construction and development of sponge cities, the problem of how to use natural precipitation to alleviate disasters such as drought and floods has become more prominent, so the development of permeable materials, especially permeable bricks, is particularly important. Most of the permeable bricks are made of industrial waste and have good physical properties. It is an indispensable part in the construction of sponge cities. [0003] The main raw materials of some permeable bricks currently on the market in my country are ceramics or ordinary permeable concrete. Ceramic permeable bricks need to use a large amount of kaolin resources. The mining of raw materials causes damage to the environment, while the production process of ceramic permeable bricks ...
