摘要: Abstract Thermal stress in mass concrete is a critical factor that used determining serviceability, and long-term durability of concrete. Phase change material (PCM) can be considered to mitigate such thermal massive structures. Based on related research results, barium-based PCM was selected as the latent heat binder. This study focuses appropriate mix design PCMs. The test results indicate application mixtures effective controlling hydration with manageable negative effects mechanical properties experimental proposed mixing methods were implemented at construction site. maximum temperature core structure maintained around 58 °C, which indicates could controlled effectively.
