For Doha port project,according to the indoor environment parameters of the tropical coastal desert climate,we use the alternating temperature and humidity chamber to simulate the tropical desert climate features for typical mix proportion of C30,C40 and C50 and study the effect on fresh concrete slump,setting time and remodeling time. The effect law of environment role factors is established on the new mix concrete construction performance,and the function relationship between environment role factors and new mix concrete construction performance is established too. Concrete temperature-stress testing is conducted to evaluate the crack resistance of concrete in mass concrete temperature field and the strong interaction constraints of boundary conditions to provide reference for the quality control of mass concrete construction for coastal tropical desert climate.
