Concrete Cooling System



• During condensation and solidification process of concrete, hydrated cement produces a large amount of hydration heat. When the heat accumulates, the temperature inside the concrete will accelerate to rise. The concrete structure is thick and large, which has low thermal conductivity and makes the heat hard to emit from the surface, therefore, the temperature difference between the inside and the outside of the concrete is excessive, besides in the early period tensile stress of concrete is weak and elasticity modulus is small, all that creates a certain of tensile stress on the concrete surface . When that tensile stress excesses the current concrete ultimate tensile strength of inside and outside concrete, the concrete surface will crack due to the temperature difference.
• In order to prevent concrete cracking, in addition to the rational proportion of all materials, construction procedure and maintenance, the most effective method is artificially temperature reduction, namely, pre-cooling the aggregate and mixing the concrete with cold water and flake ice to reduce the concrete out feeding temperature, that is the best way to control and reduce concrete pouring temperature.
•For mass concrete, expect controlling concrete pouring temperature, there is another auxiliary way by pre-embedding water pipe inside concrete to cool down concrete inner temperature by cooling water.
