Detailed Product Description

All over the world,temperture-controlled concrete is used to build large sized dykesand grout large-scale bases of high-rise buildings.In the course of maintenance,the internal intensity of concrete increases gradually with the release of water changed heat,which is not im[portant for small sized concrete structures but especially significant for the dyke projects that require the grouting of a large amount of concrete.Intthe course of maintenance,water changed heat raises the tmeperature of concrete by 25.C,causing its volume to expand.However,after maintenance,the temperature of concrete falls down and its volume reduces. The above course often brings about cracks in dykes. Therefore,the initial grouting temperature of concrete shjould be low enough to ensure that the highest temperature of concrete during maintenance does not exceed that determined by design units.Although the requirements for concrete grouting temperature vary from country to country and from construction site to construction site within the range of 7.C to 15.C,every project needs installing with complete concrete refrigerating systems.
