| Abstract: | During the hottest summer time,especially in the lower reaches of Yangtze and Yellow Rivers,as well as the coastal,the basin and desert areas in China,the concrete applied in construction wears the advantage of its faster strengthening,thus,shortening the construction period;and if the grade of the concrete is fixed,a certain amount of cement could be economized.However,in such weather the condensation crack is always a problem.This paper depicts the characteristics of condensation crack,analyzes the causes of it from both the weather conditions and the raw materials of the concete.Finally,some preventive measures and advices are put forward. |
