Aggregate grading regulator for concrete and preparation method of aggregate grading regulator
The invention discloses an aggregate grading regulator for concrete and a preparation method of the aggregate grading regulator. The aggregate grading regulator for the concrete comprises unsaturated carboxylic acid, hydrophilic unsaturated carboxylic ester, a konjac glucomannan derivative, high-branch-chain methyl beta-cyclodextrin, a polymerization-reducing foam stabilizer, an initiator, a reducing agent, a chain transfer agent and water. The aggregate grading regulator for concrete prepared by the invention effectively solves the problems of workability, cohesiveness, water-retaining property and slump retaining property of broken grading machine-made sand, makes up for grading deficiency, ensures workability and fluidity, increases water-retaining property, wrapping property, cohesiveness and thixotropy, improves homogeneity and the like, thereby improving the utilization rate of gravel aggregate and reducing the cost. The sensitivity of the influence of raw material quality fluctuation on the concrete workability is reduced, the slump loss of the concrete is reduced, and the pumpability and strength of the concrete are ensured.
本发明公开了一种混凝土用骨料级配调节剂及其制备方法，这种混凝土用骨料级配调节剂包括：不饱和羧酸、亲水性不饱和羧酸酯、魔芋葡甘糖衍生物、高支链甲基β‑环糊精、降聚稳泡剂、引发剂、还原剂、链转移剂、水。本发明制备的混凝土用骨料级配调节剂有效解决了断级配机制砂的和易性、粘聚性、保水性、保坍性，弥补级配欠缺，保证工作性、流动性，增加保水性、包裹性、黏聚性、触变性、提高匀质性等，从而提升砂石骨料利用率，降低原材料质量波动对混凝土和易性影响的敏感性，减少混凝土的坍损，保证混凝土的可泵送性及强度。
