Machine-made sand concrete mixture workability regulator and preparation method thereof
The invention relates to the technical field of concrete admixtures, and discloses a machine-made sand concrete mixture workability regulator which comprises diphenolic acid, alcohol amine, 2-methyl-2-propylene-1-alcohol, trifluoromethanesulfonic acid, unsaturated carboxylic ester, 2-acrylamido-2-methylpropanesulfonic acid, ammonium hydrogen sulfite, ammonium persulfate and deionized water. The workability regulator for the machine-made sand concrete mixture provided by the invention is good in water solubility and good in compatibility with a polycarboxylic acid water reducer, after the machine-made sand concrete mixture is doped into the machine-made sand concrete, the concrete mixture has relatively good cohesiveness and water-retaining property, the machine-made sand and gravel slurry hanging effect is good, the workability of the concrete mixture is obviously improved, and the service life of the machine-made sand concrete mixture is prolonged. The water bleeding is reduced, the concrete slump gradual loss is reduced, and the concrete slump retaining agent has good gradual slump retaining adaptability to different machine-made sand materials of concrete, especially mud-containing and powder-containing machine-made sand; in addition, the machine-made sand concrete regulator disclosed by the invention is green and environment-friendly, low in production cost and convenient to popularize and apply.
本发明涉及混凝土外加剂技术领域，公开了一种机制砂混凝土拌合物和易性调节剂，包括双酚酸、醇胺、2‑甲基‑2‑丙烯‑1‑醇、三氟甲磺酸、不饱和羧酸酯、2‑丙烯酰胺基‑2‑甲基丙磺酸、亚硫酸氢氨、过硫酸铵和去离子水；本发明提供的机制砂混凝土拌合物和易性调节剂，其水溶性好，与聚羧酸减水剂相容性好，掺入机制砂混凝土中后，混凝土拌合物具有较好的黏聚性、保水性，机制砂和碎石挂浆效果好，明显改善混凝土拌合物的和易性，减少了泌水以及降低混凝土坍落度经时损失，并且其对混凝土不同机制砂材料，特别是含泥含粉机制砂具有良好的经时保坍适应性；此外，本发明机制砂混凝土调节剂绿色环保，生产成本低，便于推广及应用。
