Abstract

The reduction of heat during cement hydration and the prediction of the formation of temperature field and stress fields in mass concrete should be considered and studied. The main objective of the paper is analysis of temperature and stress fields in the concrete mass with and without the cooling pipe system by finite element method. When the mass concrete contains the cooling pipes system, the maximum temperature, temperature difference is significantly reduced compared to the mass concrete without the cooling pipe system. At the same time, cracks do not form on the surface of mass concrete blocks. The analysis method in this study can help engineers choose one of the most effective measures to prevent the cracking formation in mass concrete structures, as is the cooling pipe system.

Keywords: temperature field, stress field, crack, mass concrete, pipe cooling
