How is temperature monitored for a mass concrete pour according to a thermal control plan?

Monitoring temperature during a mass concrete pour is critical for ensuring the material cures properly and to prevent issues such as thermal cracking. Internal sensors are the most effective method for this process as they provide real-time data on the temperature of the concrete as it hardens. These sensors are embedded within the mass of concrete and are capable of measuring temperature at various depths, which allows for a comprehensive understanding of heat generation and dissipation within the pour.

Internal temperature monitoring is particularly important in mass concrete applications, where the heat generated by the hydration of cement can create significant temperature differentials between the outer and inner portions of the concrete mass. By having internal sensors, one can accurately track this heat evolution and apply the necessary measures, such as cooling systems or insulation, to mitigate potential thermal cracking.

External sensors, infra-red lasers, and surface thermometers provide useful temperature readings but lack the depth of information that internal sensors provide. External sensors can only measure temperature on the surface of the concrete and do not account for the thermal behavior beneath the surface, while infra-red lasers are more suited for surface measurements. Surface thermometers also only provide surface temperature, which may not accurately reflect the conditions within the mass of concrete. Therefore, internal sensors are the preferred choice according to a thermal control
