温控型混凝土膨胀剂研究

Study on Thermo-regulated Type Concrete Expanding Admixture

温控型混凝土膨胀剂由钙矾石类膨胀剂和温控材料组成,具有同时补偿干缩和冷缩的功能,可抑制水泥及混凝土的水化速度,延缓到达温峰的时间,降低绝热温升,属大体积、高强度等级混凝土构件抗裂的专用新型材料。

Thermo-regulated concrete expanding admixture consists of ettringite expanding agent and thermo-regulated material.It has the function of concurrent compensation for both drying shrinkage and cooling shrinkage.It can inhibit the hydrating velocity of cement and concrete,delay the time of reaching the temperature peak and lower the adiabatic temperature rise.It is a special-purpose new break-resistant material for high strength mass concrete components.
