Water-containing manganese carbonate slag-based liquid cementing material and preparation method and application thereof

Abstract

The invention discloses a water-containing manganese carbonate slag-based liquid cementing material and a preparation method and application thereof. The method comprises the following steps: putting 80-100 parts by mass of hydrous manganese carbonate slag, 300-400 parts by mass of zirconium oxide grinding body, 32-40 parts by mass 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 into a stirring ball mill, sealing, grinding, removing the grinding body, and quickly stirring for 2-4 minutes to obtain the hydrous manganese carbonate slag-based liquid cementing material. The prepared water-containing manganese carbonate slag-based liquid cementing material has the advantages of high strength, high temperature resistance, high corrosion resistance and excellent mechanical properties. The water-containing manganese carbonate slag-based liquid cementing material can be used in the field of tunnel engineering, and solves the problem of thermal degradation of concrete materials at high temperature. The water-containing manganese carbonate slag-based liquid cementing material is excellent in high-temperature resistance and simple in preparation process, and sustainable utilization of resources is realized while the cost is reduced.

Description

Technical field[0001]The present invention relates to the field of building gelling materials, and more particularly to a hydrocarbon-containing manganese carbonate residue based liquid gelation material and a preparation method thereof.Background technique[0002]With the pace of highway construction in the western region, the number of deep bury tunnels has increased. The construction project in a complex depth environment of geological conditions will face high-ground heat, highland stress, which seriously affects the normal operation of engineering construction. With the increase in the construction depth of the tunnel engineering, highland heat and highland stress have become an issue where technical researchers are urgently needed. A large number of studies have shown that traditional cement-based materials can cause cement material degradation in high temperatures, which mainly manifest as the quality of gelling materials, forming a large number of holes and cracks and reductio...

Problems solved by technology

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
