Abstract

The invention provides a method for preparing artificial sand, gravel and sand powder by using solid waste residue, which uses industrial waste residue, activator, accelerator, high molecular polymer material and water to make inorganic gelling material, and then makes inorganic gelling material The condensate material is made into a brick body, and then crushed, screened and other subsequent processing is made into artificial sand, stones, and sand powder. The production process of the invention does not require calcination, the cost is low, and the obtained product has good performance, and can replace natural sand to prepare dry powder mortar for plastering, masonry and the like. It is conducive to the realization of construction waste slag as building materials, thereby greatly improving the economic and social benefits of solid waste slag utilization enterprises.

Description

technical field [0001] The invention relates to the technical field of artificial sand and gravel sand powder, in particular to a method for preparing artificial sand, stones and sand powder by using solid waste residue. Background technique [0002] With the rapid development of my country's construction industry, the demand for sand and stone materials continues to grow. However, the current sand and gravel materials mainly rely on natural sand and gravel, and the production areas are mainly concentrated in the main streams and tributaries of the Yangtze River and the Yellow River. In some areas, the river sand is on the verge of drying up, the supply exceeds demand, the price is soaring, and the profit is high. The most common sand and gravel has suddenly become "soft sand". Gold", stimulating the abnormal prosperity of the sand mining industry. Driven by high profits, illegal sand mining ships are rampant, and illegal operations account for nearly 50%. Excessive develo...
