Internal doping type concrete reinforcing agent and preparation method thereof

Abstract

The invention relates to the field of concrete additives, and discloses an internal doping type concrete reinforcing agent and a preparation method thereof, the internal doping type concrete reinforcing agent comprises the following raw material components by mass: 80-90 parts of deionized water, 0.2-1.0 part of potassium carbonate, 2-5 parts of calcium acrylate, 2-5 parts of a small mixed material, and 0.01-0.05 part of an antifoaming agent; wherein the small mixed material is a mixture formed by four kinds of materials including micromolecular alcohol amine substances, triethanolamine, diethanolisopropanolamine and triisopropanolamine according to any proportion. Through the synergistic effect of all the components and the cooperative use of the components and an additive, the mixture workability of concrete can be remarkably improved, full hydration of a cementing material can be promoted, and the strength of the concrete in each age is comprehensively improved; the porosity of the set cement can be reduced, the pore distribution is optimized, and the compactness is improved, so that the corrosion resistance of the concrete is improved.

Description

technical field [0001] The invention relates to the field of composite fiber materials, in particular to a built-in concrete reinforcing agent and a preparation method thereof. Background technique [0002] Concrete is an engineered composite artificial stone made of cementitious materials that bind aggregates into a whole. The cost is low. It is the preferred material in civil engineering structures and one of the most common structural forms at present. With the continuous progress of science and technology, especially the use of admixtures, the performance of concrete has been significantly improved, and the cost has been significantly reduced. In order to ensure the working performance of the concrete, with the effect of the current admixture, there is still about 20% of the cement in the concrete not fully hydrated, so the strength of the concrete cannot be further improved. In addition, with the rapid development of the construction industry and the highway and bridge...

AI Technical Summary

Problems solved by technology

[0004] 1) Existing reinforcing agent products are mostly aimed at the pure cement production process, and there are relatively few reinforcing agent products specifically for concrete. However, the material composition and performance of cement and concrete are quite different. If the cement reinforcing agent is directly If it is copied in concrete, the effect will often change greatly, and it is difficult to achieve the expected reinforcement purpose;

[0005] 2) The existing concrete reinforcing agents are not compatible with the admixtures currently used in concrete production. Some reinforcing agents are suitable for naphthalene-based water reducers, but have little effect on polycarboxylic acid and aliphatic water reducers;

[0006] 3) Some of the existing concrete reinforcing agent products are not only difficult to prepare, but also costly, and the improvement of concrete performance needs to be further improved
