A high-strength porous brick

Abstract

The invention discloses a high-strength perforated brick. The high-strength perforated brick consists of the following raw materials in parts by weight: 10-15 parts of river sand, 10-20 parts of bentonite, 5-10 parts of carbide slag, 40-50 parts of coal gangue, 10-20 parts of red stoneware shale, 10-25 parts of water, 1-5 parts of potassium perchlorate, 2-5 parts of manganese dioxide and 15-25 parts of calcite. A hollow brick obtained by crushing, sealing and ageing, blank-making, drying and roasting is strong in water absorption, unlikely to crack, high in compressive strength, excellent in comprehensive performance, accordant with the national standards, wear-resisting, anti-seismic, high in yield, capable of being directly carried and stacked, saving energy and reducing emission and preventing environmental pollution, and ecologically environment-friendly. Moreover, the high-strength perforated brick is simple in production process, convenient to manufacture, short in production period, capable of utilizing waste and saving the resources, low in production cost and beneficial to large-scale industrial production.

Description

technical field [0001] The invention relates to the field of building material production, in particular to a high-strength porous brick. Background technique [0002] The brick making industry is an industry with high energy consumption, high pollution, high resource consumption and low output. Each brick and tile factory will receive special care from the local environmental protection bureau. The sintering temperature of most brick and tile factories is about 1300-1400°C. High energy consumption. In order to solve this problem, engineers and technicians in the industry have taken many measures. Generally, enterprises adopt measures to widen and lengthen the kiln to achieve the purpose of saving energy and reducing consumption, so as to achieve rapid firing. However, the above methods require enterprises to A large amount of money has been invested in the transformation of the kiln, and the space occupied by the kiln will also be limited to a certain extent.

[0002] The brick making industry is an industry with high energy consumption, high pollution, high resource consumption and low output. Each brick and tile factory will receive special care from the local environmental protection bureau. The sintering temperature of most brick and tile factories is about 1300-1400 ℃. High energy consumption. In order to solve this problem, engineers and technicians in the industry have taken many measures. Generally, enterprises adopt measures to widen and lengthen the kiln to achieve the purpose of saving energy and reducing consumption, so as to achieve rapid firing. However, the above methods require enterprises to A large amount of money has been invested in the transformation of the kiln, and the space occupied by the kiln will also be limited to a certain extent, which is difficult to realize. Moreover, the production and use of solid clay bricks are now prohibited and restricted by the state, and excavation of soil and firing of bricks is not allowed. At present, the hollow bricks fired by other substitutes are not high in strength, not strong in water absorption, not wear-resistant, pressure-resistant, and earthquake-resistant, and the production cost is high.
