Problems solved by technology

However, the vast majority of construction waste is transported to the suburbs or villages by the construction unit without any treatment, and is stacked in the open air or landfilled, which consumes a lot of construction expenses such as land acquisition fees, garbage removal and transportation fees, and at the same time, during the process of clearing, transporting and stacking Problems such as the scattering of dust and flying dust and sand have caused serious environmental pollution.

Abstract

The invention provides a water permeable brick and a preparation method thereof. The water permeable brick is prepared from, by weight, 1350-1400 parts of aggregate materials, 399-445 parts of cement, 25-29 parts of siliceous dust, 3-4 parts of a water reducing agent and 105-135 parts of water. The aggregate materials are composed of inorganic bottom residues generated after household garbage is incinerated or gasified and building waste containing stones and broken bricks. The inorganic bottom residues and the building waste in the aggregate materials are mixed and then crushed to be aggregate with the particle size being 5-9.5 mm; part of water is utilized to wash and wet the aggregate materials in the first place, the wet aggregate materials are fed into a stirring machine to be stirred, then remaining water, cement, siliceous dust and water reducing agent are fed into the stirring machine to be stirred, forming is conducted after discharging is conducted, and the water permeable brick is obtained after curing is conducted. The water permeable brick which can be used for laying city roads is prepared from the building waste, the solid waste processing problem of the nation is solved, waste can be treated with waste, and resourceful utilization is achieved.

Description

technical field [0001] The invention relates to the field of solid waste reuse, in particular to the technology for reusing bottom slag and construction waste produced after heat treatment such as waste incineration and gasification, specifically a permeable brick prepared by using inorganic low slag and construction waste and its preparation method. Background technique [0002] Treatment technologies such as waste incineration and gasification have begun to be widely used in my country, but after heat treatment such as waste incineration and gasification, 20% to 30% of the mass of inorganic bottom slag will be produced. Therefore, the generation of a large amount of heat-treated inorganic bottom slag will also increase the burden on the increasingly tense landfills. In order to achieve "zero landfill" of waste, the comprehensive utilization of waste heat-treated inorganic bottom slag has become a feasible method. [0003] Nowadays, countries around the world have conducte...
