The invention relates to the technical field of concrete additives, and in particular, relates to a preparation process of a concrete homogenizing glue reducing agent, wherein the preparation processcomprises the steps: step 1, putting diethanolisopropanolamine, ethylene glycol and triethanolamine into a stirrer, slowly stirring at normal temperature for 30 min, adding tap water into the stirrer,and slowly stirring at normal temperature for 20 min to obtain a glue reducing agent mother liquor; and step 2, putting the glue reducing agent mother liquor and tap water into the stirrer, slowly stirring for 20 min at normal temperature, putting anhydrous sodium sulfate into the stirrer, slowly stirring for 20 min at normal temperature, and then taking sodium pyrosulfite and putting into the stirrer, and slowly stirring for 20 min at normal temperature, so as to obtain a concrete homogenizing glue reducing agent finished product, wherein the water reducing agent mother liquor is added in the first step or the second step. The concrete homogenizing glue reducing agent can disperse cement particles in waste slurry, adsorb slurry particles in the waste slurry, reduce the concentration of the waste slurry, ensure that the waste slurry is fully and effectively utilized in the concrete production process, improve the construction performance of concrete and better guarantee the strength of the concrete on site.
本发明涉及混凝土添加剂技术领域，具体为一种混凝土均化减胶剂制备工艺，第一步，取二乙醇三异丙醇胺、乙二醇、三乙醇胺，置于搅拌器中，在常温下慢拌30min，将自来水加入搅拌器中，再常温慢拌20min，得到减胶剂母液；第二步，取减胶剂母液和自来水置于搅拌器中在常温下慢拌20min，取元明粉置于搅拌器中在常温下慢拌20min，再取焦亚硫酸钠置于搅拌器中在常温下慢拌20min，即得混凝土均化减胶剂成品；其中，在第一步或第二步中加有减水剂母液。本发明的混凝土均化减胶剂能够使废浆中的水泥颗粒分散，同时吸附废浆中的泥浆颗粒，能够降低废浆浓度，能够确保废浆在混凝土生产过程中充分有效利用，提高了混凝土的施工性能，现场混凝土强度更有保障。
