A kind of artificial cultural stone using stone waste pulp as raw material and preparation method thereof

Abstract

The invention belongs to the field of resource utilization of industrial solid wastes and in particular relates to an artificial culture stone taking stone waste slurry as a raw material and a preparation method of the artificial culture stone. A blank of the artificial culture stone is prepared from the following raw material components in parts by weight: 30 to 60 parts of the stone waste slurry, 15 to 30 parts of cement, 25 to 40 parts of ceramsite, 0.1 to 0.5 percent of fiber, 0.2 to 1 part of an additive, 0 to 2 parts of pigment and 0 to 10 parts of water. The artificial culture stone is prepared from the stone waste slurry; the stone waste slurry is effectively utilized and the comprehensive utilization rate of the stone waste slurry is improved; stone waste slurry emission and pollution problems in a production process of a stone machining enterprise are solved, and sustainable development of a stone machining industry is promoted; the stone waste slurry is added so that the use amount of the cement can be reduced, the flowing degree of a mixture is increased and an air pore structure of a product is improved; therefore, the dense degree of the product can be increased, the strength and anti-freezing property of the culture stone are improved and the shrinkage rate of the product is improved. Meanwhile, the artificial culture stone is produced by the stone waste slurry and a wet mixing process is adopted; the stone waste slurry does not need to be dried; the stone waste slurry is added and the use amount of the cement is reduced, so that the cost of the raw materials is relatively low and the production cost of the culture stone product is easy to reduce.

Description

technical field [0001] The invention belongs to the field of resource utilization of industrial solid waste, and in particular relates to an artificial cultural stone using stone waste slurry as a raw material and a preparation method thereof. Background technique [0002] my country's stone industry will produce a large amount of waste stone slurry during the stone cutting process. According to different processing methods, the weight of the generated stone powder (existing in the form of waste slurry) accounts for 20% to 30% of the weight of the processed stone blocks. Stone waste slurry is difficult to use. Stone processing plants generally settle waste slurry and accumulate or transport it abroad. Some enterprises even discharge waste slurry directly to rivers and farmland. This not only occupies land resources, but also increases the cost of land acquisition and maintenance for enterprises. Small, easy to flow with the air or water, causing harm to the soil, atmosphere...

AI Technical Summary

Problems solved by technology

At present, there have been researches in China on the preparation of artificial cultural stones by using fly ash, steel slag, shale and other waste residues or waste ceramsites. The addition of these waste slags or waste ceramsites can improve the performance of artificial cultural stones, such as reducing product density, increasing strength and Improve frost resistance, etc.; at the same time, stone powder is also gradually used in the production of building decoration materials, such as the production of environmentally friendly building stones, making steles, outdoor floors, railings, guardrails, etc., but it has not been seen that stone powder is used as raw material to produce artificial culture stone report
