Description
Technical Field
The invention belongs to the technical field of concrete synergists, and particularly relates to a crystal form optimized concrete synergist mother liquor and a preparation method thereof.
Background
Cement clinker is the main raw material for producing cement. In the process of preparing clinker, a large amount of carbon dioxide and nitrogen oxides are discharged, and great damage is caused to the environment. Meanwhile, a large amount of solid wastes such as coal ash, slag, gangue, steel slag and the like are generated and accumulated, so that a large amount of land resources are occupied. Therefore, comprehensive utilization of solid wastes is imminent, and the concrete industry is the industry consuming the most solid wastes. Therefore, under the condition of ensuring that all indexes of the concrete are qualified, more industrial solid wastes are used for replacing the cement, and the preparation of the high-performance concrete has very important significance for energy conservation, emission reduction and environmental protection of the cement industry. The method is in line with the theme of 'developing circular economy, building conservation-oriented society and environment-friendly society' advocated in China at present.
After the cement is mixed with water, a multi-stage flocculation structure is formed due to the influence of charges on the surfaces of cement particles, and part of water is wrapped. And the polycarboxylic acid water reducing agent can only open a three-stage flocculation structure, a higher-stage flocculation structure can not be opened, and simultaneously cement particles can not be completely hydrated, wherein about 20 percent of cement can only be used as a filler, so that the waste of the cement is caused.

However, the grinding-aid enhancing mechanism is completely different from that of a concrete synergist, and if the concrete synergist is prepared by taking cement grinding aid raw materials as reference, the adaptability of concrete can be influenced. Meanwhile, the alcohol amine substance is greatly influenced by the price fluctuation of ethylene oxide, and the price of the alcohol amine substance is greatly influenced.
Therefore, the concrete synergist mother liquor which is simple in preparation method, low in cost, strong in reinforcement, good in stability, large in cement reducing amount and wide in adaptability is prepared, and becomes a problem which is urgently needed to be solved for realizing energy conservation and emission reduction and fully consuming solid wastes in the cement concrete industry.
