该外加剂是一种以磺化密胺树脂为减水组分 ,配以适量的引气组分、稳定组分、坍落度损失抑制组分复合而成的新型引气型高效减水剂。实验研究表明 :该外加剂满足GB80 76 - 1997《混凝土外加剂》标准中对一等品的要求 ;可以明显改善新拌砼的和易性 ,减少新拌砼坍落度损失 ,并且使砼具有优异的力学性能和耐久性能
The admixture is a novel bleed-type superplasticizer composed of a sulfonated melamine resin as a water-reducing component and an appropriate amount of an air-entraining component, a stable component, and a slump loss inhibitory component. . Experimental studies have shown that the additive meets the requirements for first-grade products in the standard of GB80 76-1997 “Concrete Additives”; the workability of fresh mixes can be significantly improved, the slump loss of new mixes can be reduced, and Excellent mechanical properties and durability
