Problems solved by technology

[0003] The technical problem to be solved by the present invention is to solve the problem of large amount of activation enhancer, high cost, poor stability, inability to effectively adjust the setting time and poor grinding effect of grinding aids in the existing cement technology in the utilization of existing industrial waste residues. Cement performance has adverse effects and poor economic benefits; and to provide an industrial waste slag activated grinding aid that can not only effectively utilize industrial waste slag, but also significantly reduce the power consumption of grinding, so that it has the advantages of less dosage, easy preparation, and effective Significant, stable and reliable outstanding advantages, greatly improve the utilization rate of industrial waste residue, improve the performance of cement, realize the purpose of saving energy and reducing consumption, protecting the environment and improving the economic benefits of enterprises

Abstract

An activating grinding aid for industrial waste residues is prepared from catalyst (1-8 wt.%), activating agent (30-80 wt.%), setting regulator (0-20 wt.%), grinding aid (3-12 wt.%) and carrier (3-30wt.%). Its advantages are effective use of industrial waste residues, low electric consumption of grinder, and improve cement performance.

Description

technical field [0001] The invention relates to a composition with catalytic activation and grinding aid functions in the new technology of industrial waste residue utilization. Background technique [0002] Activation enhancers are used in the existing industrial waste utilization technology, while grinding aids are used in the cement production process. From the existing practical application and data retrieval at home and abroad, industrial waste residue activation technology generally adopts water glass, alum, sulfate, chloride salt, nitrate and alkaline activation, the dosage is 2-10%, and the dosage is large. It has a certain early strength effect; but the stability is poor, the later strength is low, the so-called strength shrinkage phenomenon occurs, and the setting time cannot be effectively adjusted, the cost is high, and the enterprise economy is poor, so it is difficult to popularize and apply in actual production. However, the grinding aids used in the existing...
