CS-SR3超塑化剂系列

CS-SR3

DESCRIPTION

• 高力学性能与高坍落度保持的预拌混凝土；
• 高温或长时间运输条件下，高力学性能和高工作度保持的新拌混凝土；
• 强度等级达到25-70MPa以上；
• 设计防水、高耐久的混凝土工程；
• 大体积混凝土；
• 自密实混凝土；
• 其高流动性与抗离析的特征使它也适合于快速浇注混凝土工程。

WHERE TO USE

• Ready-mixed concrete with high slump retention and high mechanical performance ;
• Fresh concrete requires high mechanical performance and prolonged workability in high temperature or in long time transportation;
• Concrete with strength grade from 25 to 70MPa;
• Waterproofing and high durable concrete;
• For massive concrete;
• Self-compacting concrete;
• For fast casting concrete project benefits from its high flowing ability and bleeding resistance;

• 保持相同工作度时，可减少用水量。增进强度，降低渗透性，并提高耐久性；
• 相同水灰比下，增大工作度；
• 降低水泥水化反应速度，延长混凝土凝结时间，降低新拌混凝土工作度损失；
• 在相同水灰比与工作度下，减少用水量与水泥用量。其技术优势为低收缩﹑低徐变与低水化放热率。

      由此，根据超塑化剂CS-SR3的掺量变化(水泥重量的0.5%～1.5％)，混凝土能够达到改善工作度，延长凝结时间，长坍落度保持，降低水泥用量等目的。

TECHNICAL CHARACTERISTICS

• To reduce the amount of water while maintaining the same workability (in this manner, it is possible to increase the mechanical strength of concrete, reduce permeability, and increase durability);
• To increase the workability while maintaining the same water-cement ratio;
• To decrease the hydration velocity of cement, prolong the setting time of concrete, decrease the workability loss of fresh concrete;
• To reduce both the water and the cement content while maintaining the same water-cement ratio and the same workability. Its technical predominance are low shrinkage,low creep and low heat release rate in hydration.
