Mountain flour curing agent and preparation method thereof

Abstract

The invention discloses a mountain flour curing agent. The mountain flour curing agent is prepared from the following raw materials in parts by weight: 4 to 6 parts of gypsum, 15 to 18 parts of cement, 28 to 30 parts of quick lime, 8 to 10 parts of limestone, 30 to 35 parts of mineral powder, 1 to 2 parts of ethoxyl methyl cellulose ether, 6 to 8 parts of cast stone powder, 6 to 8 parts of ceramic micro-powder, 10 to 15 parts of furfural residue and 4 to 6 parts of medical stone. According to the mountain flour curing agent provided by the invention, mountain flour wastes are cured so that resource utilization is realized; problems that a lot of mountain flour is stacked so that a soil body is occupied and the environment is polluted and the like are solved; the mountain flour curing agent has the advantages of energy conservation and environment friendliness, low construction cost and good benefits; the cured mountain flour has good compression resistance and flexural-tensile property. Furthermore, the mountain flour curing agent provided by the invention can replace a traditional cement stirring pile, can be directly mixed with the mountain flour to carry out curing treatment, so that the construction efficiency is greatly improved and the construction cost is reduced.

Description

Technical field

[0001] The invention belongs to the field of stone powder curing, and specifically relates to a stone powder curing agent and a preparation method thereof. Background technique

[0002] With the increasing demand for stone, the waste stone powder produced by stone processing is also increasing day by day, and the accumulation of a large amount of stone powder causes a huge environmental burden. The traditional method to solve the accumulation of stone powder is to use cement as the curing agent, mix the stone powder and the stone powder, and then forcefully mix it with a stirring machine, so that the stone powder is hardened into cement soil with a certain strength. Cement soil can be used as a stone powder foundation in the construction field, which reduces the burden on the environment on the one hand, and realizes waste utilization on the other hand.

[0003] However, the unconfined compressive strength of the cement soil obtained simply by using cement as the c...
