Embodiment Construction

[0021] The present invention will be further described below.

[0022] Such as figure 1 Shown, concrete steps of the present invention are:

[0023] A. Determine the raw materials of grouting filling materials: select construction waste recycled aggregate, steel slag powder, congealed stone and composite soil as raw materials;

[0024] B. Determine the required ratio of cementing material and water (i.e. water-cement ratio): mix recycled construction waste aggregate, steel slag powder and concrete to make cementing material, and then make different proportions of cementing material and water Form multiple slurries without segregation (serum segregation occurs when the water-cement ratio reaches 0.61), and the different water-cement ratios are 0.50, 0.51, 0.52, 0.53, 0.54, 0.55, 0.56, 0.57, 0.58, 0.59 and 0.60; and then measure the fluidity of each slurry under different proportioning conditions, such as figure 2 As shown, the maximum fluidity in each slurry is obtained, an...

Abstract

The invention discloses a method for preparing a grouting and filling material by utilizing industrial solid waste. The method comprises the following specific steps: determination of raw materials ofthe grouting and filling material: selecting building waste recycled aggregates, steel slag powder, glued stone and concrete as the raw materials; respectively determining proportions of required cementing materials to water through measurement, determining the proportion of the required building waste recycled aggregates to the steel slag powder, and determining the proportion of the required concrete to the glued stone; mixing and preparing of a filling material: preparing the grouting and filling material according to the determined proportions of the cementing materials to the water, thedetermined proportion of the building waste recycled aggregates to the steel slag powder and the determined proportion of the concrete to the glued stone. According to the method disclosed by the invention, not only the problem of urban environment pollution can be reduced, but also the problems of source and cost of the grouting and filling material can also be solved, and meanwhile, the fluidityand the compression strength of the grouting and filling material both can accord with requirements.

Description

technical field [0001] The invention relates to a method for preparing a grouting filling material, in particular to a method for preparing a grouting filling material by utilizing industrial solid waste. Background technique [0002] At present, the amount of coal mining in my country is still huge, and a large amount of easy-to-source, low-cost, high-performance and less-polluting grouting filling materials are needed to realize green and scientific mining. [0003] On the other hand, with the expansion of new housing area every year in our country, a large amount of construction waste is produced. At the same time, the increase of new buildings has led to a large amount of steel produced in China, so a large amount of by-product steel slag is produced every year, and the utilization rate of steel slag is extremely low. A large amount of steel slag is discarded, occupying a large amount of land and causing waste of resources. [0004] The use of industrial solid waste to...
