Problems solved by technology

At present, most pre-mixing plants do not have a management system for waste slurry water, and lack supporting treatment and disposal equipment, which directly leads to a large amount of waste slurry water being discharged into domestic water pipes, resulting in the transition of clean water from neutral to alkaline, increasing the It is difficult to deal with, and the unhydrated particles in the waste slurry water will also hydrate and harden in an alkaline environment, blocking the sewer. In the later stage, a lot of manpower and material resources must be continuously spent to clean the sewer

Abstract

The invention belongs to the technical field of concrete functional additives, in particular to a leveling agent for mixing plant waste slurry water. prepared from raw materials. The leveling agent for waste slurry water is liquid at room temperature, has good homogeneity, meets the relevant standards for admixtures for concrete, can effectively improve the workability, compressive strength and impermeability grade of the obtained concrete, and reduces its bleeding It has important economic and environmental benefits to realize the recycling and reuse of wastewater from mixing plants.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and particularly relates to a leveling agent for waste slurry water in a mixing station. Background technique [0002] Concrete mixing water is one of the important components of cement hydration reaction, and hundreds of millions of tons of water are consumed every year to prepare cement concrete. According to statistics, the annual production of concrete is about 1 million m 3 Calculated, only cleaning the waste slurry water formed by transportation, stirring and pumping equipment, up to 100m per day 3 above. These waste pulp are difficult to deal with, usually including the following methods: 1) Direct discharge, which seriously violates environmental protection regulations and pollutes the environment; 2) After collection, it is transported to a designated location, which must be dehydrated and dried first. The bigger problem is that it takes up a large area. It also leads to ...
