Abstract

The invention discloses a lightweight fireproof building brick and a preparation method thereof. The brick is prepared from the following raw materials in parts by weight: 40 to 80 parts of industrial waste residues, 40 to 80 parts of building debris, 80 to 120 parts of wastewater, 10 to 65 parts of sludge, 10 to 50 parts of fly ash, 10 to 40 parts of river sand, 10 to 30 parts of cement, 5 to 30 parts of clay, and 1 to 20 parts of sintering aid, wherein the weight ratio of river sand to cement to clay is 2:1:1, and the sintering aid accounts for 1 to 3% of the total weight of the raw materials. The brick has a certain strength and fireproof effect. Comprehensive garbage is taken as the raw materials, wastes are recovered and utilized, the production cost is reduced, and the environment is protected.

Description

technical field [0001] The invention belongs to the technical field of building bricks, in particular to a lightweight refractory building brick. Background technique [0002] The rapid development of urbanization has also increased the increase in urban waste, and the environmental pollution has continued to worsen. The treatment methods of comprehensive waste such as construction waste, industrial waste, and domestic waste in urban development have attracted the attention of many people. Currently, landfill, incineration, and compost are used to deal with comprehensive waste. However, landfill will cause heavy metals in the waste to pollute soil and water resources; incineration will pollute the atmosphere and cause haze; composting requires additional composting equipment and operating costs . With the continuous strengthening of people's awareness of environmental protection, it is of great significance to find green and environmentally friendly technologies for dealing...
