Self-heat-insulated lightweight-aggregate module

Abstract

The invention discloses a self-heat-insulated lightweight-aggregate module. Self-heat-insulated products of different weights and strengths are produced through sintering wastes such as tailings, sludge, coal gangue, shale and pulverized coal ash so as to prepare lightweight aggregates or haydite, taking the lightweight aggregates or haydite and panned sand (the main aim is to lighten weight and improve stability and strength) as main homemade raw materials, preparing stony materials such as volcanic rock (basalt and pumice), of which the volume weight is smaller than 1,200kg, adding a certain ratio of cement as a cementing agent, and then, adding a proper foamer in a matched use manner. According to the self-heat-insulated lightweight-aggregate module, the materials used are all wastes and industrial waste residues, the disadvantage of building is overcome, and a great contribution to environmental governance is made, so that the self-heat-insulated lightweight-aggregate module is a good multipurpose product.

Description

technical field [0001] The invention belongs to the technical field of wall materials, and relates to a self-insulating lightweight aggregate module that can be used as blocks, bricks and wall panels. Background technique [0002] The construction industry is a large consumer of resources and energy, and the country consumes 4 billion tons of raw coal every year. Among them, building energy consumption (heating, cooling) accounts for about 30% of the total domestic energy consumption. [0003] Sintered brick is a material widely used in construction. Due to the great damage to land resources in the process of obtaining materials, there are still high pollution and high energy consumption in the sintering process. The production of red bricks has seriously threatened land resources and The ecological environment, specifically: [0004] 1. Large consumption of land resources: [0005] Taking Heilongjiang as an example, there are more than 1,200 sintered brick factories, wit...

AI Technical Summary

Problems solved by technology

[0006] 2. Large energy consumption and heavy pollution:

[0008] 3. The small block is big:

[0010] 4. Poor insulation performance:

[0011] The thermal conductivity of sintered clay red brick is 0.81w / m.k, the wall insulation effect of the building is poor, and the energy consumption is large

[0012] The thermal insulation methods used in buildings are all composite thermal insulation. High pollution and high energy consumption are common in the production process of composite thermal insulation materials. Inflammable, falling off, toxic, and different lifespan from buildings are common in the process of use, which increases the cost and makes construction difficult. , fall off causing personal injury, vehicle damage and other issues
