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, and after adding this reinforcing admixture to the concrete, the binding ability with water is poor, resulting in the occurrence of Decreased workability, uneven distribution of strong agents, resulting in decreased concrete strength and other issues

Abstract

The invention discloses a high-strength easily-compatible concrete reinforcing agent, which is prepared from the following raw materials in parts by weight: 12 to 16 parts of isopentenol polyoxyethylene ether, 22 to 26 parts of sodium lignin sulfonate, 2 to 4 parts of graphene dispersion liquid, 1 to 3 parts of modified starch, 1 to 3 parts of polycarboxylate superplasticizer, 1 to 3 parts of early strength agent, 2 to 4 parts of emulsifier and the like. According to the present invention, the concrete strength can be increased by 8-20%, the workability of the concrete can be effectively improved, the concrete has characteristics of bleeding resistance, no segregation, easy pumping, substantially improved freezing resistance and carbonization resistance, no toxicity, no harm, no pollution, no radioactivity, no chloride ion, no 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 the most widely 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 usually requires extra manpower and material resources for maintenance. At present, the application of industrial waste as a basic raw material in concrete is more and more extensive, especially in the production of large-scale 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. Affect the process progress such as mold turnover and prestress loading. [0003] In order to further improve the performance of concrete, a stronger agent is usually added to ...
