Abstract

The invention relates to a concrete cementitious material regulator and a preparation method thereof. The regulator includes the following components in parts by weight: 475-520kg of mixed alcohol amine grafts, 80-120kg of sodium thiocyanate, and stable dispersion Agent 40-60kg, polyphenolic compound 40-70kg and crospovidone 3-6kg, surplus is water; The preparation method comprises the following steps: S1. add water in stirring tank earlier, then add dispersion stabilizer and thiocyanate Sodium acid, the two components are fully stirred until they are completely dissolved in water; S2. Then add triethanolamine grafts, triisopropanolamine grafts, diethanolamine grafts, and cross-linked Povidone and polyphenol compounds are stirred for 15-25 minutes to obtain a finished mother liquor; S3. Finally, the finished mother liquor is diluted with water at a ratio of 1:12, and the finished concrete cementitious material regulator is prepared after stirring evenly. The invention has the effect of improving the dispersion performance of the concrete cementitious material.

Description

technical field [0001] The invention relates to the technical field of concrete additives and preparation, in particular to a concrete cementitious material regulator and a preparation method thereof. Background technique [0002] The current concrete cementitious material particles are relatively fine. When encountering mixing water, the cementitious material particles attract each other under the action of electrostatic attraction, etc., and then form a three-dimensional three-dimensional flocculation structure. About 10%-30% of the mixing water is wrapped in the flocculation structure and cannot flow freely and loses the lubricating effect, so that the fluidity of the mixture is greatly reduced. Ordinary water reducers cannot effectively disperse the flocculation structure of ultra-fine particles, but according to research, concrete cementitious material regulators can disperse these flocculation structures, make the cementitious material particles more fully contact with...
