Dry reinforced concrete and preparation method thereof

Abstract

The invention provides dry reinforced concrete. The concrete is prepared from, by weight, 55-65 parts of sand, 20-30 parts of rubber material, 10-15 parts of pelelith, 8-12 parts of barium sulfate, 5-10 parts of quartz sand, 5-10 parts of glass fibers, 3-8 parts of borax, 3-8 parts of sandstone, 3-5 parts of sodium sulfate and 3-5 parts of reinforcing agent. The rubber material is a mixture of cement powder, magnesia clay and rubber powder, wherein the weight ratio of the cement powder to the magnesia clay to the rubber powder is (5-8):(3-5):(1-3); the reinforcing agent is a mixture of siliconoxide, allophane and dry reinforcing agent, wherein the weight ratio of silicon oxide, allophane and the dry reinforcing agent is (7-13):(7-10):(3-10). The dry reinforced concrete obtained by adopting the raw materials and a method is high in strength, good in heat resistance and high in frost resistance.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to dry-strength concrete and a preparation method thereof. Background technique [0002] Concrete refers to the collective name of engineering composite materials that aggregate aggregates into a whole by cementitious materials. It is also called ordinary concrete. It is widely used in civil engineering. Concrete is one of the most important contemporary civil engineering materials. It is usually prepared by a certain proportion of cementitious materials, granular aggregates, water and admixtures, evenly stirred, densely formed, cured and hardened as a kind of artificial stone. Concrete has rich raw materials, low price and simple production process. The characteristics of concrete make it more and more used. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These charact...

AI Technical Summary

Problems solved by technology

[0003] Ordinary concrete on the market usually uses cement as the cementitious material, sand and stone as the aggregate, and the cement concrete obtained by adding water and stirring, the strength it can achieve can only meet the strength grade required for ordinary houses and road construction, but It cannot be used in large projects such as hydropower stations that require high concrete strength. Therefore, it has great market and economic significance to provide a high-strength dry-strength concrete
