Abstract

The invention relates to a concrete enhancing agent, in particular to an additive for enhancing the concrete compression strength, belonging to the technical field of an additive for construction. The concrete enhancing agent is formed by a polyacrylamide copolymer water solution and a compounding agent, wherein the polyacrylamide copolymer water solution accounts for 80-95% of the mass of the enhancing agent; and the additive accounts for 5-20% of the mass of the enhancing agent. The concrete enhancing agent disclosed by the invention has good adaptability to cement of various types and does not have rusting damage to steel bars, so that the concrete enhancing agent can be used for various prefabricated and cast-in-place concrete; and the concrete enhancing agent disclosed by the invention has the good adaptability to other commonly-used additives, and the strength grade of the concrete can be obviously improved after the suitable amount of the concrete enhancing agent is added into the concrete.

Description

technical field [0001] The invention relates to a concrete reinforcing agent, in particular to an admixture for enhancing the compressive strength of concrete, and belongs to the technical field of admixtures for construction. Background technique [0002] Compared with cement mortar, concrete is obviously superior in terms of strength and durability after curing, so concrete structures are widely used. Generally speaking, the strength of concrete structures can be improved by adding admixtures for improving permeability in concrete structures. Concrete admixtures can be divided into the following four categories according to their main functions: ①Admixtures to improve the rheological properties of concrete mixture, including ordinary water reducers and high-efficiency water reducers, air-entraining agents and pumping agents; ②Adjustment of concrete setting time, Admixtures for hardening properties, including retarders, early strength agents and accelerators; ③Admixtures t...
