High-strength light hollow brick and preparation process thereof

Abstract

The invention discloses a high-strength light hollow brick and a preparation process thereof, and relates to the field of hollow bricks. The hollow brick is prepared from the following raw materials in parts by weight: 70 to 130 parts of dehydrated river mud, 50 to 110 parts of blast furnace slag, 30 to 70 parts of kaolin, 10 to 30 parts of expanded perlite, 5 to 25 parts of glazed hollow bead, 5 to 25 parts of red porcelain shale, 5 to 15 parts of ceramic fiber, 5 to 15 parts of shell charcoal powder, 4 to 12 parts of calcium formate, 4 to 8 parts of hydroxyethyl methyl cellulose, 3 to 7 parts of methyl methacrylate, and 5 to 15 parts of cement-based permeable crystallization type water-proofing agent, wherein the water content of the dehydrated river mud is 15 to 25 percent; the hollow brick is 40 percent in hole ratio; the hole pattern is a rectangular hole pattern; the hollow brick is prepared by mixing materials, aging, casting, molding, dicing, drying, airing with sunlight and maintaining. The high-strength light hollow brick has the advantages of low raw material cost, simple preparation process, energy saving, environmental friendliness, high pressure resistance and low density.

Description

technical field [0001] The invention relates to the field of hollow bricks, in particular to a high-strength lightweight hollow brick and a preparation process thereof. Background technique [0002] With the rapid development of the national economy and the continuous improvement of people's living standards, the consumption of energy is also increasing, and the problem of energy shortage is becoming more and more prominent. Therefore, people pay more and more attention to energy-saving and environmentally friendly building materials. One of them is widely used. Usually, the lower hollow brick is made of clay, shale, etc. as the main raw materials, which are processed, shaped and sintered. The percentage of the total area of ​​holes in the hollow brick to the area of ​​the brick where it is located is called the porosity of the hollow brick, which should generally be above 40%. Compared with solid bricks, hollow bricks can save a lot of land, soil and fuel for burning brick...

AI Technical Summary

Problems solved by technology

However, the current existing hollow bricks have the disadvantage of low compressive strength, so that the buildings made of hollow bricks have poor earthquake resistance, and there are certain hidden dangers of collapse. In addition, the existing hollow bricks have complicated production processes and high energy consumption, resulting in increased production costs.
