Pressure-resistant sintered brick

Abstract

The invention discloses a pressure-resistant sintered brick, and belongs to the field of building materials. The method comprises the following steps of: mixing the blast furnace slag with sulfate solution; freezing and crushing the mixture to improve the dispersibility of the blast furnace slag, wherein SiO2 contained in the blast furnace slag can act with CO2 at high temperature to generate silicon carbide to play a reinforcing role; introducing water vapor, oxidizing the silicon carbide to generate pores for SiO2, alternately improving the structural stability, and improving the pressure resistance; coating, granulating and sintering by using a coating liquid containing potassium permanganate components, wherein the internal metal components can be melted at high temperature to generatemetal oxides, the fluidity of the metal oxides can improve the bonding strength among the internal components, and nano SiO2, nano Al2O3 and nano Fe are used as a substrate layer, the composite bonding material and the gecko-imitating carbon nano-tube structure are manufactured, so that the improvement of pressure resistance is ensured. The pressure-resistant sintered brick solves the problem that the prior sintered brick has poor pressure resistance due to poor balance of the self structure to porosity and internal mechanical property.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a pressure-resistant sintered brick. Background technique [0002] In the construction industry, wall materials are an important part of the construction industry, and the consumption of wall materials is the largest among building materials. In recent years, with the rapid advancement of urban construction, the annual consumption of wall bricks is more than 600 billion pieces, about 660,000 mu of land, and 90 million tons of standard coal. Under the dual effects of environmental protection requirements and policy regulations, promoting new wall materials, reducing land occupation, eliminating clay brick production capacity, and saving land is the general trend of environmental protection requirements, and the environmental protection innovation of the wall material industry is inevitable. With the increasing scarcity of land resources, most areas have given up the use of clay ...
