High-efficiency solid waste-based cementing activity excitant

Abstract

The invention relates to an efficient solid waste-based cementing activity activator, and relates to the field of material science and solid waste resource utilization. The problem that solid waste such as red mud, coal gangue and tailings is difficult to utilize is mainly solved, and the high-performance red mud-based cementing material is prepared. The efficient red mud-based cementing activityactivator comprises 40 to 60 parts of alkali metal silicate, 10 to 20 parts of alkali metal hydroxide, 0 to 15 parts of a high-calcium solid waste material, 4 to 8 parts of carbonate, 0 to 5 parts ofhydrotalcite and 0 to 8 parts of an imidazole porous crystal material. The prepared red mud-based cementing material has the advantages of high mechanical strength, short setting time and the like.

Description

technical field [0001] The invention belongs to the fields of material science and solid waste resource utilization, and particularly relates to a high-efficiency solid waste-based gelling activity stimulator. Background technique [0002] The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. [0003] At present, with the rapid development of my country's economy, a large amount of cement-based cementitious materials are required for a large number of projects. Traditional cement materials have the disadvantages of high energy consumption, high pollution, high cost, and non-renewable raw materials. Therefore, the research and development of solid waste-based cementitious materials has become a research hotspot in t...

AI Technical Summary

Problems solved by technology

Traditional cement materials have disadvantages such as high energy consumption, high pollution, high cost, and non-renewable raw materials. Therefore, the research and development of solid waste-based cementitious materials has become a research hotspot in the field of cement cementitious materials.

However, solid waste has the disadvantage of low activity, which limits its use in construction projects.
