Ultraviolet resistant concrete and preparation method thereof

Abstract

The invention discloses an ultraviolet resistant concrete. The ultraviolet resistant concrete is prepared by using the following raw materials, 110-120 parts of cement, 2-5 parts of magnesium oxide, 14-17 parts of an acrylic emulsion, 20-25 parts of glazed hollow beads, 3-8 parts of sodium benzoate, 5-8 parts of benzotriazole, 90-110 parts of fly ash, 100-130 parts of volcanic rock, 15-19 parts of polystyrene foam particles, 35-50 parts of waste clothes, 4-8 parts of an aid and a proper amount of water. The addition of benzotriazole, glazed hollow beads and the acrylic emulsion to concrete makes the concrete effectively resist ultraviolet ray and prevent corrosion, so the steel bar corrosion is effectively prevented, and the quality of the concrete is improved; and the fly ash and the volcanic rock are added to substitute parts of natural sandstone aggregate, so the cost is saved, the environment is protected, and the ultraviolet resistant concrete has an extremely high popularization application value.

Description

[0001] technical field [0002] The invention relates to the technical field of building concrete, in particular to an anti-ultraviolet 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 conc...

[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
