Analysis of factors influencing the temperature field variation in mass concrete during hydration heat release
Mass concrete is prone to cracks due to the temperature difference between the inside and outside. In this study, the effects of four factors, including the ambient temperature, initial temperature of concrete after pouring, and cooling water temperature and flow rate, on the variation characteristi...

| description | Mass concrete is prone to cracks due to the temperature difference between the inside and outside. In this study, the effects of four factors, including the ambient temperature, initial temperature of concrete after pouring, and cooling water temperature and flow rate, on the variation characteristics of the internal temperature field of mass concrete are investigated using a combination of theoretical, empirical, and numerical simulation analyses. The results show that the service life of concrete can be prolonged by lowering the ambient temperature, lowering initial temperature of concrete after pouring, increasing the cooling water temperature or increasing the cooling water flow rate, which can effectively improve the cooling rate of concrete. The temperature difference between the inside and outside of the concrete can be effectively reduced by increasing the ambient temperature, increasing the cooling water flow rate, lowering initial temperature of concrete after pouring, or lowering the cooling water temperature, thus reducing the possibility of cracks. Through Grey relation analysis, it is found that cooling water temperature is the most important influencing factor that affects the changing characteristics of the internal temperature field of concrete The influencing factor weights can be used to provide theoretical support for subsequent temperature control measures. |
