Compound type exciting agent and preparation method thereof

Abstract

The invention relates to an additive for concrete and in particular relates to the additive which is mainly applied to a concrete mixture system added with a mineral admixture in the field of the concrete and has an exciting effect on the mineral admixture. The invention designs a compound type exciting agent; auxiliary agents including a water reducing agent, a defoaming agent, a viscosity reducer and the like are added on the basis of the exciting agent to participate in preparation; the exciting agent prepared by the invention has a good exciting effect on the mineral admixture and cement;the dosage of the mineral admixture can be increased in a utilization process, so that the production cost is reduced and the property of the concrete also can be enhanced. The compound type excitingagent is applied to a concrete system; two substances including fly ash and mineral powder are mainly used as the admixture and various exciting type chemical substances are added to prepare the compound type exciting agent; the substances with the exciting effect are mutually stacked to use so that the corresponding effects are mutually complemented to reach the maximum exciting effect.

Description

technical field [0001] The invention relates to an external additive for concrete, in particular to an external additive which is mainly used in a concrete mixture system in which mineral admixtures are added in the field of concrete and has an exciting effect on the mineral admixtures. Background technique [0002] In the current construction process of human basic engineering, the use of building materials is becoming more and more diversified, but in the use of many building materials, the use of concrete materials still occupies a large share, mainly because in many Among the building materials, concrete is a kind of building material with low price and easy to control product performance. Therefore, in the current construction projects, concrete construction is still widely used as a building material. However, with the continuous development of science and technology and economic level, how to make concrete building materials efficient and environmentally friendly has ...

[0004] However, when mineral admixtures are used in concrete engineering, although there are a large amount of active substances in the mineral admixtures, it is difficult to play a role in the process of use. Therefore, when using mineral admixtures, it is necessary to add Other activating substances activate active components in mineral admixtures

[0005] Chinese Invention Patent Publication No. CN1386715A discloses a method for making a cement strength stimulator. In this patent, an organosilicon reinforcing agent and a cement additive with an early-strength effect are used to prepare it with the addition of lanthanum and cerium rare earth elements. There is this patent The prepared cement activator has a good stimulating effect and can effectively stimulate the strength of cement, but rare earth elements are used in the preparation process, and the cost of rare earth elements is relatively high, and the cost is relatively high in the process of use. In addition, the activator prepared by this patent only stimulates the strength of cement, which has a single performance for the use of concrete soil materials
