Anti-thermal cracking is one of key issues for construction quality control of mass concrete. This paper introduced an intelligent monitoring technology of anti-thermal cracking for mass concrete. The temperature cooling process was optimized by thermal stress tests conducted on the temperature-stress testing machine. The real-time evaluation and prediction models targeting on adequate concrete temperature were established based on the real-time collected information at different stages of mixing, casting, cooling and insulation. The models can achieve precise index monitoring and dynamic warning of concrete temperature, and control concrete parameters such as temperature automatically and intelligently. The technology shows a good application effect on the mass concrete temperature control optimization and real-time monitoring, and it can be popularized in the similar projects.
