我国外加剂技术在不断地更新和发展,其中聚羧酸外加剂正以较快地发展速度让预拌混凝土行业接受并广泛投入使用,但是聚羧酸产品质量本身还存在一定的质量缺陷。采用一些萘系和脂肪类外加剂调整的方式和小料对聚羧酸这种产品进行调整,已经失去了意义,需要从一个全新的角度进行适应性调整,怎么去克服这种缺陷而更好地发挥聚羧酸本身的优势,本文通过一些实践调整案例分析聚羧酸不适应调整和研究结果。 The technology of admixture in our country is continuously updated and developed. Polycarboxylic admixture is being accepted and widely used by ready-mixed concrete industry at a relatively fast speed. However, the quality of polycarboxylic acid product still has certain quality defects. The use of some naphthalene and fat additives to adjust the way and small material on the polycarboxylic this product has been adjusted to lose its meaning, need to be a whole new perspective of adaptive adjustment, how to overcome this defect and better To play the advantages of polycarboxylic acid itself, this article through some practical adjustments case analysis of polycarboxylic acid does not adapt to the adjustment and research results.
