Stimulation reinforcer with high volume industrial waste residue powder used for concrete and its preparation method

Abstract

The invention belongs to the concrete preparation technical field, and relates to a stimulation reinforcer with high volume industrial waste residue powder used for concrete. The stimulation reinforcer comprises the following raw materials by mass percentage: 30-60% of dispersed stimulation ingredient, 0.01-1% of early strength ingredient, 10-30% of reinforcement ingredient, 0.01-1% of set-regulating ingredient and the balance of water. A preparation method comprises the following steps: successively adding water, the dispersed stimulation ingredient, the early strength ingredient, the reinforcement ingredient and the set-regulating ingredient, stirring for 20-30 minutes until complete dissolution. The prepared stimulation reinforcer is capable of stimulating the activity of the industrial waste residue powder, under the premise of ensuring each performance of the concrete, the industrial waste residue powder is a substitution of the cement, the method has simple and reasonable preparation and is easy for production, the prepared concrete has the advantages of high compression strength and good durability.

Description

technical field [0001] The invention belongs to the technical field of concrete preparation, and relates to a large-volume industrial waste slag powder excitation enhancer for concrete and a preparation method thereof. Background technique [0002] Concrete is the most used building material in the world. Due to the advantages of cheap and easy raw materials, diversity and adaptability in application and high economy, it is widely used in various buildings and has become the foundation of modern society. As the largest developing country in my country, in recent years, with the steady growth of the national economy, the scale of national infrastructure has become larger and larger, and the demand for concrete is huge. [0003] The large number of applications of concrete has led to an ever-increasing production of cement as its main component. As we all know, the cement industry is an industry with high energy consumption, high emission and high pollution. Statistics show ...

AI Technical Summary

Problems solved by technology

[0006] The utilization rate of industrial waste residue in developed countries in foreign countries has reached more than 70%, while the domestic utilization rate is lower than 40%.

The application of industrial waste slag activators has a history of decades of development in foreign countries, but it started late in China and the application effect is not ideal

[0007] At present, most of the activator products in the domestic market are made of inorganic materials or simple compounding of inorganic and organic materials, which have the problems of large dosage, high cost, low stability, poor excitation effect and adaptability
