High-strength hollow brick and preparation method thereof

Abstract

The invention discloses a high-strength hollow brick, consisting of the following raw materials in parts by weight: 20-35 parts of construction waste, 10-20 parts of purple sand shale, 40-50 parts of coal gangue, 30-35 parts of phosphogypsum and 10-15 parts of water, the hollow brick is obtained by crushing, sealed ageing, blank making, drying and sintering, and the obtained hollow brick is strong in water absorption, good in fire prevention and heat preservation performances, high in compressive strength, excellent in comprehensive performance, meets the national standards, has wear resistance and seismic resistance, can be directly carried and stacked and is high in yield; the effects of energy conservation and emission reduction are achieved, thereby preventing environmental pollution and protecting the ecological environment; moreover, the high-strength hollow brick is simple in production process, convenient to make, short in production period, low in production cost and conducive to industrial mass production.

Description

[0001] technical field [0002] The invention relates to the field of building material production, in particular to a high-strength hollow brick and a preparation method thereof. Background technique [0003] The brick-making industry is an industry with high energy consumption, high pollution, high resource consumption and low output. Every brick and tile factory will receive the key care of the local environmental protection bureau. Now the production of hollow bricks will consume a lot of resources, which is not in line with the principle of resource conservation. For example, the sintering temperature of most brick and tile factories is about 1300-1400 ℃, and the energy consumption is high. In order to solve this problem, the engineering and technical personnel of the industry have taken many measures. Generally, enterprises take measures to widen and lengthen the kiln to achieve The purpose of saving energy and reducing consumption is to achieve rapid firing, but t...

[0003] The brick-making industry is an industry with high energy consumption, high pollution, high resource consumption and low output. Every brick and tile factory will receive the key care of the local environmental protection bureau. Now the production of hollow bricks will consume a lot of resources, which is not in line with the principle of resource conservation. For example, the sintering temperature of most brick and tile factories is about 1300-1400 ℃, and the energy consumption is high. In order to solve this problem, the engineering and technical personnel of the industry have taken many measures. Generally, enterprises take measures to widen and lengthen the kiln to achieve The purpose of saving energy and reducing consumption is to achieve rapid firing, but the above method requires enterprises to invest a lot of money in the transformation of the kiln, and the space occupied by the kiln will also be limited to a certain extent, it is difficult to realize, and it is not allowed now Excavating earth and firing bricks, now using other substitutes to make bricks requires adding cement, which is costly, and the hollow bricks of fired bricks are not strong in water absorption, wear-resistant, pressure-resistant, and earthquake-resistant, and cannot meet the needs of society
