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, and particularly relates to a homogenizing agent for mixing station waste slurry water, which is prepared by taking a dispersing component, a workability adjusting component, a mud inhibiting component, a pH value adjusting component and water as main raw materials. The homogenizing agent for the waste slurry water is in a liquid state at normal temperature, is good in homogeneity, meets related standards of admixtures for concrete, can effectively improve the workability, compressive strength and impermeability grade of the obtained concrete, reduces the bleeding rate of the concrete, realizes recycling of wastewater of a mixing station, and has important economic and environmental benefits.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular 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 the preparation of cement concrete will consume hundreds of millions of tons of water every year. According to statistics, the annual production of concrete is about 1 million m 3 Calculated, only cleaning the waste slurry water formed by transportation, mixing and pumping equipment, up to 100m per day 3 above. These waste pulps are difficult to deal with, and usually include the following methods: 1) direct discharge, which seriously violates environmental protection regulations and pollutes the environment; 2) after collection, it must be dehydrated and dried before being transported to a designated place. The bigger problem is that it will occupy a large area The site an...
