Mass concrete construction technology of high-rise building foundation platform

摘要

In order to avoid harmful mass concrete cracks, in the construction of International Cultural and Educational Center, Qiqihar University, the mass concrete construction technology of foundation platform is discussed. It consists mainly of the following processes, Include selecting raw materials and additives, such as using large size coarse aggregate, while reducing the amount of mud in the sand, adding the right amount of fly ash, UEA and other additives in the cement of low heat of hydration. Also include using a stratified sub-construction process. In addition, arranging temperature measurement tube and calculating internal temperature of concrete, etc. It is an effective technology in reducing hydration heat and thermal stress, and achieving significant results on the control of mass concrete cracks.
