High-strength easily-compatible concrete reinforcing agent

Abstract

The invention discloses a high-strength easily-compatible concrete reinforcing agent which comprises the following raw materials in parts by weight: 12-16 parts of isopentenol polyoxyethylene ether, 22-26 parts of sodium lignin sulfonate, 2-4 parts of graphene dispersion liquid, 1-3 parts of modified starch, 1-3 parts of a polycarboxylate superplasticizer, 1-3 parts of an early strength agent, 2-4parts of an emulsifier and the like. According to the invention, the strength of concrete can be increased by 8%-20%, the workability, bleeding resistance, no segregation and easy pumping of the concrete can be effectively improved, the frost resistance and carbonization resistance are greatly improved, and the concrete reinforcing agent is non-toxic, harmless, pollution-free, radioactivity-freeand free of chloride ions, alkali and the like.

Description

technical field [0001] The invention belongs to the technical field of concrete admixtures, in particular to a high-strength and easily compatible concrete strengthening agent. Background technique [0002] Concrete is currently the most used building material in the world. It has the main advantages of low price, strong bearing capacity and high durability. However, the early strength of concrete develops slowly, and it usually requires extra manpower and material resources for maintenance. At present, industrial wastes are used as basic raw materials in concrete more and more widely, especially in the production of large prefabricated components, a large number of mineral admixtures such as mineral powder and fly ash are used, and the early strength of concrete develops more slowly , affecting process progress such as mold turnover and prestress loading. [0003] In order to further improve the performance of concrete, it is usually used to add a strong agent to it in th...

AI Technical Summary

Problems solved by technology

[0004] At present, the reinforcing admixture in the existing concrete materials has a single function, mainly to improve the early strength, and has almost no contribution to the later strength. After adding this reinforcing admixture to the concrete, the binding ability with water is poor, which leads to the failure of the concrete when it is mixed. Decreased workability, uneven distribution of strong agents, resulting in decreased concrete strength and other problems
