Product introduction 產(chǎn)品簡介
High performance water-reducing agent is currently the largest and most widely used high-efficiency water-reducing agent in China. It is characterized by a high water-reducing rate (15%~25%), no air-entraining, and a small impact on the setting time. It is suitable for cement Relatively good performance, can be used in combination with various other additives.
High performance water-reducing agents are often used to formulate high-fluidity, high-strength, and high-performance concrete. In use, it can greatly reduce the water consumption and significantly increase the strength of concrete at various ages. It can also save 10% or more of cement while maintaining a constant strength, which is cost-effective.
In addition, the High performance water-reducing agent also has a small chloride ion content and does not corrode the steel bars; it can enhance the impermeability, freeze-thaw resistance and corrosion resistance of concrete, and improve the durability of concrete.
高效減水劑是我國目前生產(chǎn)量最大,使用最廣的高效減水劑,其特點是減水率較高(15%~25%),不引氣,對凝結(jié)時間影響小,與水泥適應(yīng)性相對較好,能與其他各種外加劑復(fù)合使用。萘系減水劑常被用于配制大流動性、高強、高性能混凝土。使用中既能大幅度降低用水量從而顯著提高混凝土各齡期強度。又能在保持強度恒定時,節(jié)約水泥10%或更多,性價比較高。此外,高效減水劑還具有氯離子含量微少,對鋼筋不產(chǎn)生銹蝕作用;能增強混凝土的抗?jié)B、抗凍融及耐腐蝕性,提高混凝土的耐久性等特點。

Precautions for use 使用注意事項
1、The content of this product (solid content 20%) is 0.6% to 2.0% of the total weight of the cementitious material. The usual dosage is 0.8%~1.5%. Before use, a trial mix test of concrete should be carried out to find the best mixing amount.
本產(chǎn)品的摻量為膠凝材料總重量的0.6%—2.0%。常用摻量為0.8%—1.5%。使用前應(yīng)進行混凝土試配試驗,以求最佳摻量。
2、When using this product, the measurement must be accurate, and the concrete must be mixed evenly.
使用本產(chǎn)品時,必須計量準確,混凝土必須攪拌均勻。
3、The superplasticizer has a strong dispersing effect on the cement, which can greatly improve the fluidity of the cement mixture and the slump of the concrete, and at the same time greatly reduce the water consumption and significantly improve the workability of the concrete. However, some superplasticizers will accelerate the loss of concrete slump, and excessive mixing will cause bleeding.
高效減水劑對水泥有強烈分散作用,能大大提高水泥拌合物流動性和混凝土坍落度,同時大幅度降低用水量,顯著改善混凝土工作性。但有的高效減水劑會加速混凝土坍落度損失,摻量過大則泌水。
