Ecological cement for plateau region

Abstract

The invention discloses ecological cement for a plateau region. The ecological cement is characterized by comprising a powder material and an additive, wherein the powder material is at least one of calcareous rock, limestone, cinerite, volcanic pumice, basalt, illite, montmorillonite, feldspar, shale, kaolin, clay, wollastonite, coal gangue, silica fume and coal ashes; and the additive is at least one of halide, carbonate, sulfate, amine alkaline matter, silicate, aluminate, alkali metal hydroxide and alkaline earth metal hydroxide. The ecological cement is high in strength, the main mechanical performance index is superior to that of glass and cement, and the ecological cement is comparable with metal materials such as ceramic and aluminum steel. The ecological cement has relatively high corrosion resistance and relatively good durability and is greatly superior to a traditional cement material. The ecological cement has relatively good quick hardening and curing property, is in high temperature resistant, good in heat insulation effect, is relatively low in heat conductivity coefficient and is comparable with a light refractory clay brick.

Description

technical field [0001] The invention relates to cement, in particular to ecological cement used in plateau areas. Background technique [0002] All building materials can change from slurry to hard solid through a series of physical and chemical actions, or after being mixed with other substances (such as water, etc.), and can convert granular materials ( Such as sand, stone, etc.) or blocks, sheet materials (such as bricks, stones, etc.) cemented into a whole substance, called cementitious material. [0003] Cement is currently the most commonly used cementitious material. However, on the one hand, cement production consumes a lot of energy, accounting for 15% of the world's total energy consumption. my country's annual cement production is more than 200 million tons, ranking first in the world, but my country's cement unit energy consumption It reaches 5280KJ / kg, which is 60% higher than the average unit energy consumption of cement in the world, which is 3260KJ / kg.

[0003] Cement is currently the most commonly used cementitious material. However, on the one hand, cement production consumes a lot of energy, accounting for 15% of the world's total energy consumption. my country's annual cement production is more than 200 million tons, ranking first in the world, but my country's cement unit energy consumption It reaches 5280KJ / kg, which is 60% higher than the average unit energy consumption of cement in the world of 3260KJ / kg, and the problem of energy consumption in production is particularly prominent

On the other hand, our country is very rich in various mineral resources, and there is a large backlog of industrial waste residues, occupying a large area of ​​land and polluting the environment, which urgently needs to be developed and utilized.
