Problems solved by technology

This surface enhancer is composed of two components. The obtained surface enhancer can significantly improve the surface strength of hardened concrete. It has the effects of filling, compacting, strengthening, and sealing. However, the surface reinforcement prepared by this patent The agent is divided into two components, AB, which need to be painted separately during use, so the workload of the project is relatively large

Abstract

The invention relates to a concrete additive, in particular to a concrete surface reinforcement repair agent. The concrete surface reinforcement repair agent is composed of the following substances inpercentages by weight: 40% to 60% of methacrylic acid-methyl acrylate polymer, 20% to 40% of deionized water, 0.4% to 0.6% of carboxylic acid, 4% to 6% of colloid silicon oxide, 2% to 4% of magnesiumstearate, 8% to 12% of coal ash, 0.4% to 0.6% of silicate and 1% to 2% of anhydrite. The concrete surface reinforcement repair agent disclosed by the invention can be quickly permeated to the interior of concrete to reach the effect of effectively improving the using strength of concrete.

Description

technical field [0001] The invention relates to a concrete admixture, in particular to a repairing agent for surface reinforcement applied to concrete. Background technique [0002] In the actual construction process of concrete engineering, the type of cement, the water-cement ratio of concrete and even the use of some admixtures that affect the strength of concrete will affect the strength of concrete. For projects that also have clear requirements on the lightness of concrete, how to better maintain or even improve the strength of concrete requires the introduction of other additives to participate in the adjustment. Surface enhancers can play a very good role in increasing the strength of concrete. Therefore, in recent years, the research and use of surface enhancers have attracted more and more attention. [0003] Chinese Invention Patent Publication No. CN104557137A discloses the preparation of a concrete surface strengthening agent. This invention designs a two-comp...
