Inorganic binding material prepared through classified treatment of building solid waste recycled aggregate and preparation method of inorganic binding material

Abstract

The invention discloses an inorganic binding material prepared through classified treatment of building solid waste recycled aggregate and a preparation method of the inorganic binding material. The building solid waste recycled aggregate is taken as aggregate for producing inorganic binding material products with different strength. By means of a technology, an inorganic binding material stabilizing material is produced from building solid waste with processes of sorting, pre-wetting, impurity removal, crushing, sieving, secondary prewetting, storage, batching and stirring. By means of the technology for disposing the building solid waste, waste bricks and concrete in the building solid waste are converted into recycled aggregate through a specific processing procedure with sufficiently studied characteristics of the building solid waste, and inorganic binding material stabilized building solid waste recycled aggregate products are formed in cooperation with an inorganic binding material by plant mix, blending and stabilizing; a manual soring platform is fixed on a sieving equipment main body, large light substances are manually picked out, tiny particles and light substances areremoved through an air separation device, and impurity ingredients in the building solid waste are effectively removed.

Description

technical field [0001] The invention relates to the technical field of construction waste recycling, in particular to an inorganic binder produced by classified processing of construction solid waste recycled aggregates and a preparation method thereof. Background technique [0002] With the rapid development of urban construction in our country, the reconstruction, expansion and demolition of various buildings such as old city reconstruction and new city expansion have produced a large amount of construction solid waste. With the expansion of cities, a large number of new municipal roads and highways And other engineering projects have consumed limited mine resources. The discharge of construction solid waste and the gradual depletion of mine resources have brought about a series of issues related to natural resources, environmental protection and sustainable development; with appropriate technology, construction solid waste can be used as road construction materials and be...

Problems solved by technology

[0005] The invention provides an inorganic binder made by classified processing of recycled construction solid waste aggregates and a preparation method thereof, aiming at solving the problem of unclassified and mixed processing of construction solid waste in the prior art, and the performance of the processed aggregates will be relatively large. Variability, resulting in unstable quality of the produced mixture, low quality, technical problems that cannot be upgraded to a high-level application level, and the product can only be used as a low-grade stable material with a low-strength level, and the recycling range is narrow. It reduces the recycling value of construction waste as a valuable urban mine resource of high-quality stone and concrete, causing secondary waste
