A kind of hydrous manganese carbonate slag-based liquid gelling material and its preparation method and application

Abstract

The invention discloses a hydrous manganese carbonate slag-based liquid gelling material and its preparation method and application. Parts of water, 112-140 parts by mass of phosphoric acid, 8-10 parts by mass of titanium slag, 8-10 parts by mass of iron ore powder and 2-3 parts by mass of grinding aid are packed into a stirring ball mill for sealing, grinding, removing the grinding body, and stirring quickly 2-4min, one-step method to obtain hydrous manganese carbonate slag-based liquid gelling material. The prepared hydrous manganese carbonate slag-based liquid gelling material has high strength, high temperature resistance, strong corrosion resistance and excellent mechanical properties. It can be used in the field of tunnel engineering and solves the problem of thermal degradation of concrete materials at high temperatures. The hydrous manganese carbonate slag-based liquid gelling material has excellent high temperature resistance, simple preparation process, and realizes sustainable utilization of resources while reducing costs.

Description

technical field [0001] The invention relates to the technical field of building cementitious materials, in particular to a water-containing manganese carbonate slag-based liquid cementitious material and a preparation method and application thereof. Background technique [0002] With the accelerating pace of highway construction in the western region, the number of deep-buried tunnel projects has increased. Construction projects in a buried deep environment with complex geological conditions will face the problems of high geothermal heat and high geostress, which seriously affect the normal progress of the project construction. As the construction depth of tunnel engineering increases, the problems of high geothermal heat and high geostress have become urgent problems to be solved by researchers skilled in the art. A large number of studies have shown that heating of traditional cement-based materials at high temperatures will lead to the degradation of cement materials, wh...

This method has excellent performance, but the cost is too high

[0006] The Chinese invention patent application with the publication number CN110903046A discloses a method for preparing building cementitious materials with electrolytic manganese metal leaching slag. Improving the activity of electrolytic manganese slag can fully stimulate its gelling performance, and the prepared building cementitious materials are It can be made into cement masonry mortar, plastering mortar, dry-mixed mortar, external wall plastering mortar, unburned brick, etc., which reduces the amount of cement in the cementitious material, can adjust the setting time of the cementitious material, and has high strength , health and environmental protection, reduce costs, and improve the economic benefits of enterprises, but the preparation process is complicated and the operation process is long

[0007] The above three gelling materials all have the following defects, the preparation process is complicated, the process line is long and the economy is not high, the gelling material produced is not resistant to high temperature and has poor thermal stability, and the gelling material is easy to degrade at high temperature
