Abstract

The invention relates to the field of building concrete and in particular relates to a concrete admixture. With the adoption of the technical scheme of the invention, the concrete admixture consists of the following components in percentage by weight: 20-30 percent of triethanolamine, 3-5 percent of tartaric acid, 12-25 percent of ferric trichloride, 8-12 percent of sodium chloride, 22-25 percent of cane sugar, 5-10 percent of surfactant and 20-35 percent of sodium dodecyl sulfate. On the basis of the scheme, the concrete admixture consists of the following components in percentage by weight: 22 percent of triethanolamine, 4 percent of tartaric acid, 13 percent of ferric trichloride, 8 percent of sodium chloride, 22 percent of cane sugar, 7 percent of surfactant and 24 percent of sodium dodecyl sulfate.

Description

technical field [0001] The invention belongs to the field of building concrete, in particular to a concrete admixture. 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.
