Preparation method of machine-made sand concrete regulator
The invention discloses a preparation method of a machine-made sand concrete regulator, and belongs to the field of concrete admixtures, the regulator obtained by the preparation method of the machine-made sand concrete regulator contains a large number of anionic groups, has small molecular weight and strong diffusivity, can be adsorbed prior to water and a high efficiency water reducing agent, and occupies adsorption vacancies, so that the surface energy of high-adsorbability stone powder and fine particles in concrete is effectively reduced, water adsorption and consumption of high-adsorbability machine-made sand are overcome to a great extent, formation of a local flocculation structure is effectively avoided, and compared with the prior art, the anti-collapse performance of the machine-made sand during concrete preparation is remarkably improved;through the setting of a gas oscillation mechanism, the reaction speed in the preparation process of the regulator is remarkably increased, the production time is shortened, and the preparation efficiency is greatly improved.
本发明公开了一种机制砂混凝土调节剂制备方法，属于混凝土外加剂领域，一种机制砂混凝土调节剂制备方法，本方法得到的调节剂中含有大量的阴离子基团，其分子量较小，扩散能力强，可优先于水、高效减水剂进行吸附，占据吸附空位，有效地降低了混凝土中高吸附性石粉、细颗粒的表面能，很大程度上克服了高吸附性机制砂对于水吸附和消耗，有效避免局部絮凝结构的形成，相较于现有技术显著机制砂在制备混凝土时的保塌性，另外通过气荡机构的设置，显著提高了在本调节剂制备过程中的反应速度，缩短生产时间，大幅度提高制备效率。
