Abstract

The invention discloses a composition with catalytic activatable and grinding aid function at the same time in industrial residue utilizing new technique, which comprises the following steps: allocating mass percent as 1-8% accelerant, 30-80% activator, 0-20% regulated set agent, 3-12% grinding aid and 3-30% carrier; getting the product. This invention adopts catalytic activator technique, which overcomes the defects of harsh terms of industrial waste slag and high clinker request.

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...
