Description
Technical Field
The invention belongs to the technical field of concrete admixtures, and particularly relates to a high-strength easily-compatible concrete synergist.
Background
Concrete is the most used building material in the world at present, and has the main advantages of low price, strong bearing capacity, high durability and the like. However, the early strength of concrete develops slowly, and the concrete is usually cured by extra manpower and material resources. At present, industrial wastes are used as basic raw materials to be applied to concrete more and more widely, especially mineral admixtures such as mineral powder and fly ash are used in large-scale prefabricated part production, the early strength of concrete develops more slowly, and the process progress such as mold turnover and prestress loading is influenced.
In order to further improve the performance of concrete, a reinforcing agent is usually added into the concrete in the prior art, and the reinforcing agent has two main functions, namely, the dispersibility of the concrete material is increased, so that particles of the concrete material can be fully dispersed, the particles are prevented from being agglomerated together, the hydration process of cement is further accelerated, the using amount of the cement in the concrete is reduced, and the adsorption capacity of other concrete additives such as a water reducing agent on the concrete material is increased, so that the using effect of the concrete material is enhanced.
The existing reinforcing admixture in the concrete material has single function, mainly improves early strength and hardly contributes to later strength, and after the reinforcing admixture is added into the concrete, the bonding capacity with water is poor, so that the problems of workability reduction during concrete mixing, uneven distribution of a strong agent, concrete strength reduction and the like are caused. Therefore, it is necessary to develop a concrete reinforcing agent with high strength and easy compatibility.
