Anti-freezing concrete and preparation method thereof

Abstract

The invention belongs to the field of building concrete, and particularly relates to a concrete admixture. The concrete admixture comprises components in percentage by weight as follows: 20%-30% of triethanolamine, 3%-5% of tartaric acid, 12%-25% of iron trichloride, 8%-12% of sodium chloride, 22%-25% of sucrose, 5%-10% of a surfactant and 20%-35% of sodium dodecyl sulfate. The multifunctional concrete admixture is reasonable in prescription and convenient to use, so that cement concrete can have the performance of water reduction, delayed coagulation, early strength, flexural strength, impermeability, anti-freezing, pumping and wear resistance.

Description

technical field [0001] The invention relates to building concrete, in particular to an antifreeze concrete and a preparation method thereof. Background technique [0002] Concrete is one of the most important civil engineering materials today. It is composed of cementitious materials, granular aggregates (also known as aggregates), water, and additives and admixtures added when necessary, prepared in a certain proportion, uniformly stirred, densely formed, cured and hardened. artificial stone. Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make it widely used, not only in various civil engineering, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an important material....

AI Technical Summary

Problems solved by technology

[0004]With the continuous development of the economy, more functional concrete is needed, such as antifreeze concrete, to prevent concrete from freezing damage and reduce engineering accidents; salt corrosion resistant concrete, to avoid Sulfate and chloride salts contained in saline soil will cause corrosion to the concrete in roads and bridges, etc. At present, there are many researches on functional concrete, but most of them cannot achieve the desired effect, some are due to the combination of The effect is not obvious due to the problem of the composition of the ingredients. Some of them are because the ingredients in the components are relatively complicated, which is not easy to store in use, and it is more complicated to use.
