High-performance plastic-retaining mortar additive and preparation method thereof
The invention discloses a high-performance plastic-retaining mortar additive and a preparation method thereof, and belongs to the field of mortar additives. The additive is prepared from the following raw material components in parts by mass: 85 to 115 parts of zeolite micro powder compound for loading, 30 to 40 parts of polycarboxylic acid water reducing agent, 12 to 18 parts of sodium gluconate treated by sodium periodate, 4.5 to 5.5 parts of triethanolamine and 1.8 to 2.2 parts of polyoxyethylene polyoxypropylene ether. The plastic-retaining mortar additive disclosed by the invention can reduce the shrinkage rate of mortar, the plastic-retaining mortar additive disclosed by the invention is added according to the dosage of 0.55 wt% of the cement dosage, the 28d shrinkage rate is tested according to the methods in GB/T25181-2019 and JGJ/T70-2009, and the 28d shrinkage rate is 0.11-0.12%.
本发明公开一种高性能保塑型砂浆添加剂及其制备方法，属于砂浆添加剂领域。所述添加剂的原料按质量份计，包括以下组分：负载用沸石微粉复合物85‑115份、聚羧酸减水剂30‑40份、高碘酸钠处理的葡萄糖酸钠12‑18份、三乙醇胺4.5‑5.5份、聚氧乙烯聚氧丙醇胺醚1.8‑2.2份。本发明的保塑型砂浆添加剂可以降低砂浆的收缩率，将本发明的保塑型砂浆添加剂按照掺量为水泥用量的0.55wt%进行添加，并按照GB/T25181‑2019、JGJ/T70‑2009中的方法测试28d收缩率，28d收缩率为0.11‑0.12%。
