Autoclaved sawn mud concrete building block and processing technique thereof

Abstract

The invention discloses an autoclaved sawn mud concrete building block and a processing technique thereof, belongs to a building material and a production and processing process thereof, and particularly relates to an engineering building block taking sawn mud generated in a stone sawing and processing process as a manufacturing raw material and a processing technique thereof. The building block is characterized by comprising the following raw materials in percentage by weight: 70 to 82 percent of sawn mud, 14 to 22 percent of lime, 3 to 14 percent of cement, 0.8 to 1.8 percent of gypsum and 0.06 to 0.12 percent of aluminum powder, wherein the water cement ratio is 0.5 to 0.68 / 1. The technique manufactures the high-quality material used in the building industry by fully using a large amount of waste, namely the sawn mud generated in the stone processing industry; and the technique has considerable economic benefit, reduces the pollution emission of the stone processing industry to theenvironment to a great extent, and meanwhile has good social benefit.

Description

technical field [0001] The invention belongs to a building material and its production and processing technology, in particular to an engineering block made of sawing mud generated during the stone sawing process and its processing technology. Background technique [0002] At present, in civil engineering, the most widely used wall blocks are fly ash aerated concrete blocks and quartz sand aerated concrete blocks, and the main raw materials are fly ash and quartz sand. in, [0003] Raw material ratio of fly ash aerated concrete block: [0004] Fly ash 70% to 80%, lime 15% to 22%, cement 3% to 7% [0005] Gypsum 0.8%~1.8% Aluminum powder 0.06%~0.12% Water cement ratio 0.5~0.65 / 1 [0006] Quartz sand aerated concrete block raw material ratio: [0007] Quartz sand 68%~76%, lime 13%~21%, cement 8%~14% [0008] Gypsum 0.8%~1.6% Aluminum powder 0.06%~0.12% Water cement ratio 0.5~0.68 / 1 [0009] Visible, in above-mentioned existing wall body block, the consumption of fly ash...

AI Technical Summary

Problems solved by technology

[0009] Visible, in above-mentioned existing wall block, the consumption of fly ash and quartz sand is very large

The prices of these two materials are relatively high, and with the continuous increase in consumption and the implementation of resource control policies, their prices will continue to rise

On the other hand, sawing mud is the main waste in the stone processing industry, and its generation is very large, and there is no way to reuse it at present

The common practice is to discharge in situ, thus causing serious pollution to the local air and water environment
