The concrete admixture disclosed by the invention has the beneficial effects that the concrete admixture can be used for improving the peaceability, the durability of concrete can be improved, and the strength of the concrete is improved.

Description

A kind of concrete admixture

Technical field

The present invention relates to a kind of concrete admixture.

Background technology

Concrete admixture mixes in the concrete process of mixing, and in order to improve the material of concrete performance, according to the regulation of Its Relevant Technology Standards, its incorporation is not more than 5% of cement quality.The Main Function of concrete admixture improves the performance of fresh concrete and improves the performance of maturing.Admixture can improve concrete performance effectively, and has good economic benefit. and be all widely used in many countries, become material indispensable in concrete.The use of especially high-effect minimizing agent. cement particle can be disperseed fully, water consumption greatly reduces, cement potential is not fully exerted. and cause Behavior of Hardened Cement Paste comparatively fine and close, pore structure and interface region microstructure are well improved, thus concrete physical and mechanical property is greatly improved.A kind of water reducer efficiently of research and development of people's effort.

Summary of the invention

For the deficiencies in the prior art, the technical problem to be solved in the present invention is, provides a kind of concrete admixture, can improve workability. concrete weather resistance can also be improved, and improve concrete intensity.

For solving the deficiencies in the prior art, the technical scheme that the present invention takes is: a kind of concrete admixture, is made up of the raw material of following parts by weight:

Sodium sulfate 8-15 part, urea 3-9 part, 2-hydroxy-butanedioic acid 9-16 part, ethylene bis stearamide 4-11 part, Surfactant OP-103-8 part, oxyacetic acid 6-8 part, ethylene glycol 3-6 part, pure acrylic latex 7-11 part, sulfamate 3-8 part, M-nitro benzoic acid 4-7 part, sodium lauryl sulfate 6-10 part, Sodium Silicofluoride 5-10 part.

The invention has the beneficial effects as follows that concrete admixture of the present invention can improve workability. concrete weather resistance can also be improved, and improve concrete intensity.
