Geopolymer terrace base material

Abstract

The invention relates to the technical field of construction materials, and aims to provide a geopolymer terrace base material. The base material is prepared by mixing and stirring the following raw materials in parts by weight: 30 to 50 parts of fine sand, 30 to 50 parts of mixture composed of blast furnace slag and steel slag according to a mass ratio of 3:1, 5 to 15 parts of meta-kaolin, and 2 to 5 parts of cement clinker. According to the preparation method, blast furnace slag is used to replace cement as the main gelatinization raw material of terrace, the preparation cost of terrace is reduced, the wastes are converted into valuable resource; high hardness steel slag is used to replace aggregate such as broken stone, cobblestone, and the like, the wastes are utilized, the wear resistant property of base material is enhanced; the production technology is simple, toxin-free, and harmless; and the terrace base material has the advantages of high wear resistant property, high luster, difficulty in generating dusts or sand, short maintenance time, and excellent decorative effect.

Description

technical field [0001] The invention belongs to the field of structures and buildings, and in particular relates to a geopolymer floor base material. Background technique [0002] Geopolymer materials are inorganic geopolymers formed by polymerizing aluminosilicate oxides in the presence of alkaline activators. The structure contains Si-O-Al bonds and has gelling properties. At present, the floor of various buildings is generally made of ordinary cement concrete, which is easy to dust and sand after completion, and has almost no gloss. And the production of the used hydraulic cement needs to be calcined at extremely high temperature, which will produce a large amount of carbon dioxide. It is generally believed that the production of 1 ton of hydraulic cement produces about 1 ton of CO 2 , while the formation of 1 ton of geopolymer cementitious material only produces about 0.1 ton of CO 2 , so in contrast, the geopolymer material that basically uses all solid waste raw mat...

AI Technical Summary

Problems solved by technology

[0003] At present, there have been reports in this field that geopolymer materials are used as stone and wood floors, which have the advantages of fast, low cost, non-toxic, moisture-proof and anti-slip, etc., but the integrity, surface gloss and impermeability are poor, so they cannot be used in factories. , garages and other places that require higher surface performance

Another report pointed out that the geopolymer mass concrete prepared with metakaolin, mineral powder, and fly ash as the main raw materials has the advantages of temperature cracks, low incidence of shrinkage cracks, and good durability. Disadvantages such as low surface gloss and insufficient wear resistance

The method of adding active high-hardness steel slag particles based on geopolymer materials to make floor substrates with good wear resistance and high gloss has not been reported yet.
