Description

Technical Field

[0001] The present invention relates to the field of material science, and in particular to a method and system for improving the utilization rate of waste concrete slurry based on polycarboxylic acid molecules. Background Art

[0002] Improving the utilization rate of waste concrete slurry means that through a series of technical means and management measures, the waste slurry generated in the concrete production process (such as mixing station cleaning wastewater, concrete mixer truck cleaning wastewater, etc.) can be effectively treated and recycled, reducing the discharge of waste slurry and increasing its reuse ratio, thereby achieving the goals of energy conservation, emission reduction and environmental protection.

[0003] At present, the utilization rate of concrete waste slurry is mainly improved through sedimentation and separation, which is to let the solid particles in the waste slurry settle in the sedimentation tank and extract the supernatant. This method is inefficient and has a slow processing speed. When large-scale production is required, the utilization rate of waste slurry cannot be improved in time, resulting in poor improvement of the utilization rate of concrete waste slurry. Polycarboxylate (PCE) is a high-efficiency water reducer that can increase fluidity, improve working performance and increase strength in concrete. Therefore, it is necessary to consider optimizing the structure of the polycarboxylate molecule itself to improve the utilization rate of concrete waste slurry. Summary of the invention
