Anticorrosive concrete and preparation method thereof

Abstract

The invention discloses an anticorrosive concrete. The anticorrosive concrete is prepared by using the following raw materials, by weight, 100-120 parts of cement, 80-105 parts of river sand, 12-15 parts of dimethicone, 6-9 parts of tolyltriazole, 1-3 parts of lithium carbonate, 2-5 parts of sodium fluosilicate, 90-100 parts of coal gangue, 80-110 parts of building waste, 30-50 parts of old clothes, 4-8 parts of an aid, and a proper amount of water. The addition of tolyltriazole and dimethicone to the concrete makes the prepared concrete have an anticorrosive effect and good cohesiveness, effectively prevents the corrosion of steel and improves the quality of concrete, and coal gangue and building waste are added to substitute parts of natural sandstone aggregate, so the anticorrosive concrete has the advantages of cost saving, environment protection and extremely high application value.

Description

[0001] technical field [0002] The invention relates to the technical field of building concrete, in particular to an anti-corrosion concrete and a manufacturing method thereof. Background technique [0003] Concrete usually uses cement as the cementitious material, sand and stone as aggregates, mixed with water (may contain admixtures and admixtures) in a certain proportion, and the cement concrete obtained by mixing is also called ordinary concrete. The advantages of forming, low energy consumption, good durability, low price, and combining with steel can be made into various load-bearing mechanisms. It is the most widely used building material in contemporary times and plays a very important role in the development of human society. [0004] As one of the necessary additives to concrete, the amount of aggregate used is very large, and the natural aggregate is over-exploited, so that its quality cannot meet the needs of existing concrete production. At present, the concre...

[0004] As one of the necessary additives to concrete, the amount of aggregate used is very large, and the natural aggregate is over-exploited, so that its quality cannot meet the needs of existing concrete production. At present, the concrete still has poor strength, low frost resistance, large drying shrinkage, and is prone to Insufficiency such as cracking
