Inorganic mineral polymer self-leveling mortar and preparation method thereof

Abstract

The invention relates to inorganic mineral polymer self-leveling mortar and a preparation method thereof. The mortar mainly comprises the raw materials in parts by weight: 64-72 parts of mine residues, 18-22 parts of kaolin, 10-14 parts of fly ash, 20-25 parts of water glass, 8-12 parts of sodium hydroxide, 25-30 parts of water, and 190-260 parts of fine sand, wherein additives are a water reducing agent, a stabilizing agent and an antifoaming agent; gelating materials adopt inorganic mineral polymers which are made from the mine residues, the kaolin and the fly ash and stimulated by the water glass with a specific modulus of 1.4-1.5; because of a dimensional net structure in the inorganic mineral polymers, the self-leveling mortar disclosed by the invention has higher compressive strength, higher rupture strength and durable and abrasion-proof performance. The 28d compressive strength is 45MPa, the 28d rupture strength is 9MPa, and the cohering strength is 4.5MPa. The mortar disclosed by the invention also solves the problems that the surface is not smooth after the mortar is hardened, the surface is cracked after being retracted, the surface is hollow and peeled; moreover, the utilization rates of industrial by-products are also improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to an inorganic mineral polymer self-leveling mortar and a preparation method thereof, which is a preparation method of the self-leveling mortar using an inorganic mineral polymer as a cementitious material. Background technique [0002] Ordinary cement-based self-leveling mortar is composed of cement, fine aggregate, filler and admixture, etc. It is a self-leveling material with high fluidity after adding water. It has good fluidity and self-leveling function, and can be quickly solidified. It can be constructed on the floor material in a short time. It is firmly bonded to the substrate and has good characteristics such as high compressive strength. In recent years, not only has it been widely used in self-leveling floors, but it has also been greatly developed as a final finishing material. However, cement-based self-leveling mortar still has technical defects such as ...

Problems solved by technology

At present, the discharge of solid waste in my country is becoming more and more serious, but the utilization rate of industrial solid waste is less than 50%, and the utilization rate of mine tailings is less than 5%. The main raw material for preparing mineral solidified materials is solid aluminosilicate, which can be used in various Aluminosilicate minerals and industrial solid waste
