Cement concrete admixture capable of rapidly repairing cement concrete road

Abstract

The invention comprises a cement admixture composition. The formula comprises the following raw materials in parts by weight: 5.3-7.4 parts of bentonite, 11-16 parts of sodium gluconate, 35-48 parts of beta-based sodium sulfonate formaldehyde condensates, 13-17 parts of sodium sulphate, 0.2-1.3 parts of rosin smoke, 0.6-1.8 parts of magnesium powder, 2.6-3.4 parts of alkylbenzene sulfonate, 14-21parts of triethanolamine, 12-17 parts of a silane coupling agent, 5.8-6.9 parts of ethylene glycol, 13.5-15.9 parts of sodium dodecylbenzene sulfonate, 1.3-2.9 parts of a polycarboxylate water-reducer, 2.5-12.7 parts of methylcellulose, 11-19 parts of pure acrylic latex, 13-15 parts of polyacrylamide, 0.9-4.3 parts of silicone and 2.8-6.4 parts of calcium chloride. The peaceability of concrete canbe improved. The durability of the concrete can further be improved, and meanwhile, the intensity of the concrete is improved.

Description

technical field [0001] The invention relates to a concrete admixture composition and belongs to the technical field of concrete. Background technique [0002] At present, there are many kinds of concrete admixtures available in the market, and there are some defects in actual use: First, although the water-reducing effect is good, the bleeding rate increases, which affects its quality uniformity; second, it has poor adaptability to cement varieties , It is easy to cause early setting of concrete, which affects the normal construction of the project. The existing concrete admixtures generally have high costs, unstable performance, and complex formulas, which cannot be easily obtained. For this reason, we propose a kind of concrete admixture composition. Contents of the invention [0003] Aiming at the problems of the prior art; the invention provides a concrete admixture composition. [0004] The technical solution adopted in the present invention is: a concrete admixture...
