Calculation of Temperature Rise of Mass Concrete and Modification of Formula

Abstract:

With the continuous improvement of China’s construction technology, the application of mass concrete structures is increasingly popular in various structures in order to meet the requirements of structure and function, such as tall buildings, dams, railways and highways. There are all kinds of cracks in construction process because of the big cross section. There are many reasons to form cracks, but temperature is the most common cause. It is vital to the construction quality of mass concrete that the hydration heat, especially the peak value of temperature rise, is calculated in advance and precautions are implement in construction process accordingly. In this article, the calculation formula modified is derived through analyzing the common calculation formulas of mass concrete, the actual measurement results and the influencing factors of temperature rise.
