Environment-friendly slump retaining type concrete pumping agent and preparation method thereof
The invention discloses an environment-friendly slump retaining type concrete pumping agent. The concrete pumping agent is characterized by comprising the following components in parts by weight: 20-30 parts of a furfuryl methacrylate/N-vinylcarbazole phosphate/beryllium acetylacetonate/vinylbenzenesulfonic acid copolymer, 0.5-1.5 parts of gamma acid waste liquid, 2-5 parts of sodium glycyrrhizinate, 1-3 parts of glycerol ester of rosin, 1-3 parts of a surfactant, 1-2 parts of dolomite, 2-5 parts of carboxyl modified beta-cyclodextrin and 35-45 parts of water. The invention further discloses apreparation method of the environment-friendly slump retaining type concrete pumping agent. The environment-friendly slump-retaining type concrete pumping agent disclosed by the invention is remarkable in slump retaining and water reducing effects, small in mixing amount, good in stability and cement adaptability, capable of effectively improving the durability of concrete, free of bleeding, goodin plasticity retaining performance and pumping performance, free of obvious negative effects on the comprehensive performance of the concrete, and green and environment-friendly in preparation and use processes.
本发明公开了一种环保保坍型混凝土泵送剂，其特征在于，包括如下重量份计的各组分：甲基丙烯酸糠酯/磷酸基N‑乙烯基咔唑/乙酰丙酮铍/乙烯基苯磺酸共聚物20‑30份、γ酸废液0.5‑1.5份、甘草酸钠2‑5份、松香甘油酯1‑3份、表面活性剂1‑3份、白云石1‑2份、羧基修饰β‑环糊精2‑5份、水35‑45份。本发明还公开了所述环保保坍型混凝土泵送剂的制备方法。本发明公开的环保保坍型混凝土泵送剂保坍和减水效果显著，掺量少，稳定性和与水泥适应性好，能有效提高混凝土耐久性，不泌水，保塑性能和泵送性能佳，对混凝土综合性能无明显负面影响，制备和使用过程中绿色环保。
