Study on Temperature Control Method of Yeywa Hydropower Station RCC Dam Construction

摘要

Yeywa hydropower station RCC dam is located in the torrid zone of Asian, During the construction period, it meet Technical problem of temperature control in hot season. We can utilize the peculiarity of RCC that has a slow temperature rise due to hydration heat and a low early strength, according to analyse the blending and concreting procedure of RCC, adopt comprehensive and effective temperature control method, such as confirm concrete mix, control the temperature of raw material and RCC out of the batch plant, prevent temperature rise during transporting and concreting, setting joint to avoid structural crack and temperature crack. From Yeywa hydropower station RCC dam construction finished to now, no dangerous crack is detected, It accumulate experiences for RCC dam construction in high temperature place.
