Titanium dioxide doped concrete and preparation method thereof

Abstract

The invention discloses a titanium dioxide doped concrete. The titanium dioxide doped concrete is prepared by using the following raw materials, by weight, 90-120 parts of cement, 80-100 parts of gravel, 30-40 parts of desulfurized gypsum, 10-13 parts of rubber particles, 9-11 parts of epoxy resin, 8-10 parts of isocyanate, 5-8 parts of titanium dioxide, 2-4 parts of sodium silicofluoride, 95-125 parts of waste concrete, 80-100 parts of fly ash, 2-4 parts of sodium nitrate, 40-50 parts of waste clothes, 4-8 parts of an assistant and a proper amount of water. The aggregate of the titanium dioxide doped concrete prepared in the invention contains waste concrete and fly ash, so the consumption of natural sandstones is reduced, the utilization rate of the natural sandstones is improved, and the production cost is reduced; and the addition of titanium dioxide and waste cloth fibers to the raw materials for preparing the titanium dioxide doped concrete increases the toughness and the radiation resistance of the concrete, and makes the prepared concrete have the advantages of unlikely cracking, good workability, high compressive strength, high temperature resistance and the like.

Description

[0001] technical field [0002] The invention relates to the technical field of building concrete, in particular to concrete mixed with titanium dioxide and a preparation 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.

[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
