Concrete gravel aggregate regulator and preparation method thereof
The invention provides a concrete gravel aggregate regulator which comprises the following raw materials in parts by weight: 15-30 parts of a modified polycarboxylic acid water reducer, 1-3 parts of sodium carboxymethyl cellulose, 2-5 parts of hydroxypropyl methyl cellulose, 0.5-3 parts of a retarder and 1-4 parts of an activating agent. According to the preparation method, the polycarboxylic acid water reducing agent with excellent slow release performance is synthesized by improving the preparation method of the polycarboxylic acid water reducing agent, the comprehensive performance of the concrete gravel aggregate conditioning agent is improved by compounding multiple components, and the preparation method of the concrete gravel aggregate conditioning agent is simple, easy to operate and suitable for industrial production. The concrete sandstone aggregate conditioning agent is convenient for large-scale production and use, has been used in actual constructional engineering, and has good effects.
本发明提供了一种混凝土砂石骨料调节剂，按重量份计，包括以下原料，15～30份的改性聚羧酸减水剂，1～3份羧甲基纤维素钠，2～5份羟丙基甲基纤维素，0.5～3份缓凝剂和1～4份活化剂。本发明通过改进聚羧酸减水剂的制备方法，合成具有优异缓释性能的聚羧酸减水剂，本发明通过多种成分的复配，提高了混凝土砂石骨料调节剂综合性能，本发明提供了一种混凝土砂石骨料调节剂的制备方法，简单易于操作，便于大规模的生产和使用，本发明的混凝土砂石骨料调节剂已在实际建筑工程中使用并取得良好的效果。
