A kind of glass fiber mixed concrete and preparation method thereof

Abstract

The invention discloses a glass fiber mixed concrete. The glass fiber mixed concrete is prepared by using the following raw materials, 100-120 parts of cement, 2-5 parts of sodium hyposulfite, 45-70 parts of coarse quartz sand, 7-11 parts of a glass fiber, 2-5 parts of magnesium oxide, 3-6 parts of potassium oxide, 15-18 parts of asbestos wool, 10-13 parts of hydroxyethyl cellulose, 60-80 parts of quicklime, 70-90 parts of expanded perlite, 35-50 parts of waste and old clothes, 3-6 parts of an assistant and a proper amount of water. The aggregate of the glass fiber mixed concrete prepared in the invention contains quicklime and expanded perlite, so the consumption of natural sandstones is reduced, the production cost is reduced, and the prepared concrete has the advantages of unlikely cracking, good workability, improvement of the pore structure and the pore gradation, and improvement of the impervious capability, and can be applied in the building engineering to enhance the earthquake-proof performance of structures.

Description

technical field [0001] The invention relates to the technical field of building concrete, in particular to a glass fiber mixed concrete and a manufacturing method thereof. Background technique [0002] 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. [0003] 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 stil...

[0003] 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
