| Abstract: | 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. |

| Keywords: | Concrete Adiabatic temperature rise Temperature control Expanding admixture |
