( CSCEC-PAULY Construction Company Limited, Beijing 100023, China)Abstract: Kongzhong Huaxi Village project is a transfinite high-rise building composed of hotel-style apartments and ancillary public facilities. lt has a total construction area of 212987.42m2. The building is a landmark project in Huaxi Village, is also a symbol of China's rural areas. The Building is frame-tube structure system, with a total height of 328m. In this four meter-thick mass concrete construction, the temperature difference between inside and outside the concrete is effectively controlled and the emergence of the concrete cracks are prevent, through taking measures such as optimizing concrete mix, setting cooling pipe, the use of polystyrene foam insulation board, electronic thermometer testing concrete center temperature and Optimization ofthe construction site management.
Keywords: mass concrete; cooling pipe; polystyrene foam board; electronic thermometer; crack control
