Abstract

The invention discloses a solid degassing agent for concrete and a preparation method of the solid degassing agent. The degassing agent is prepared from 40-60% of a carrier, 10-30% of fatty alcohol polyoxyethylene polyoxypropylene ether fatty acid ester, 10-30% of polyether modified polysiloxane and 5-15% of fatty alcohol polyoxyethylene polyoxypropylene ether carboxylate. According to the concrete defoaming agent, fatty alcohol polyoxyethylene polyoxypropylene ether fatty acid ester and polyether modified polysiloxane are used as defoaming substances, and fatty alcohol polyoxyethylene polyoxypropylene ether carboxylate with a specific structure is introduced, so that the defoaming agent has a defoaming enhancement effect in concrete; meanwhile, the compatibility between the two defoaming substances, namely the fatty alcohol polyoxyethylene polyoxypropylene ether fatty acid ester and the polyether modified polysiloxane, and other additives of the concrete can be improved, and the product has excellent compatibility and defoaming performance.

Description

technical field [0001] The invention belongs to the technical field of additives for concrete, and relates to a solid degasser for concrete and a preparation method thereof. Background technique [0002] In order to improve the quality of concrete, various cement additives, such as air-entraining agents and water reducing agents, are often used. The air-entraining agent is to improve the fluidity of unhardened concrete by introducing air bubbles in the concrete, improve the workability of the construction and the frost resistance of the hardened concrete. Water reducing agent can improve the fluidity of concrete and reduce the water content of concrete, and the reduction of water content can improve the strength of concrete. However, if the amount of air introduced into the concrete increases, coarse air bubbles are likely to be generated, resulting in uneven filling and a decrease in the strength of the concrete, and voids will be formed on the surface of the hardened conc...
