Abstract

The invention relates to the technical field of concrete, in particular to a concrete additive. The concrete additive comprises the following components in parts by weight: 10-30 parts of modified cement, 10-20 parts of modified bentonite, 1-3 parts of nanometer silicon dioxide, 1-5 parts of a water reducing agent, 0.3-0.8 part of alkyl sodium sulfonate, 10-20 parts of gypsum powder, 1-5 parts of a wet dispersing agent, 0.3-0.8 part of a stabilizing agent, 0.2-0.5 part of an anti-freezing agent, 1-6 parts of a corrosion inhibitor and 10-25 parts of deionized water. The concrete additive has the beneficial effects that the compressive property of concrete can be greatly improved, and meanwhile, the durability of the concrete can be improved; the modified cement and the modified bentonite are utilized, so that the penetrating performance is greatly improved; besides, the corrosion inhibitor and the anti-freezing agent are added, so that performances of concrete are improved from multiple aspects, the service life of the concrete is prolonged, and the maintenance cost of a concrete building is reduced.

Description

Technical field [0001] The invention involves the field of concrete technology, especially a concrete additive. Background technique [0002] Concrete is one of the most important civil engineering materials in contemporary contemporary.It is made by the gel material, granular collection material (also known as aggregate), water, and the outer agent and mixture that are added if necessary, stirred through a certain proportion, is uniformly stirred, densely forming, and maintenance and hardening.Planting artificial stone.The concrete has the characteristics of rich raw materials, low prices, and simple production technology, so it makes it more and more dosage.At the same time, concrete also has the characteristics of high pressure resistance, good durability, and wide range of strength.These characteristics make it widely use, not only in various civil engineering, but also the shipbuilding industry, the mechanical industry, the development of the ocean, geothermal engineering, e...
