preparation example Construction

[0041] The present application also provides a method for preparing the above-mentioned all-solid waste dry-mixed mortar, comprising the following steps in sequence:

[0042] 1) Mix and grind the fly ash and steel slag, and obtain a powder material A after the mixing and grinding is completed, wherein the fineness of the powder material A is controlled to be 45 μm and the sieve residue is 4wt% to 6wt%;

[0043] The slag and gypsum are mixed and ground, and the powder material B is obtained after the mixing and grinding is completed, wherein the fineness of the powder material B is controlled so that the sieve residue of the 45 μm sieve is greater than zero and less than 1wt%;

[0044] The ceramic waste and slag are mixed and crushed, and the fine aggregate is obtained after the mixing and crushing is completed, wherein the maximum particle size of the fine aggregate is controlled to be less than 2.36mm;

[0045] 2) mixing the powder material A prepared in step 1) with the powd...

Abstract

The invention provides a full solid waste dry-mixed mortar which is formed by mixing various raw materials. The raw materials comprise flying ash, steel slag, mineral slag, gypsum, ceramic waste material and furnace slag. The invention also provides a preparation method of the full solid waste dry-mixed mortar. Through three approaches of optimizing the varieties and content of solid wastes insidethe solid waste mortar, reasonably carrying out mixing and matching according to grain composition and optimizing the preparation method, formula optimization is combined with process optimization, the preparation of the full solid waste dry-mixed mortar is realized, practice indicates that the full solid waste dry-mixed mortar improves the addition proportion of solid wastes inside the mortar, and also solves the problem that the mortar is non-uniform caused by low consistency, high shrinkage, easy cracking, hollowing and material separation existing in the solid waste mortar prepared by adding water into the full solid waste dry-mixed mortar, so that the application range of the solid waste inside the mortar is enlarged.

Description

technical field [0001] The invention relates to the technical field of resource utilization of solid waste, in particular to an all-solid waste dry-mixed mortar and a preparation method thereof. Background technique [0002] Solid waste pollutes the environment in many ways, and the stockpiling of solid waste causes land, water, soil and air pollution. The most effective measure to solve solid waste resources is to use solid waste to prepare building materials, but solid waste Solid waste shows many shortcomings in the application of building materials, which makes it difficult to popularize and utilize solid waste. [0003] At present, in the prior art, there are solid wastes used to prepare cementitious materials, or construction wastes used to prepare fine aggregates and use them alone in mortar, or only a small part of solid wastes are used in the preparation of mortars. Materials were reported using solid waste. [0004] At present, in the prior art using solid waste ...
