In Equation 2, Tea means the equivalent age, and Ta means the average curing temperature of concrete during dt time. Ts means 293 degrees Celsius, and represents the result of adding the absolute temperature (K) + 20 degrees Celsius. E is the activation energy determined by the type of cement. For example, in the case of Type 1 cement, when Ta is 20 ° C or less, the activation energy is determined to be greater than 33.5 KJ / mol, and when Ta is 20 ° C or more, the activation energy is determined to be 33.5 KJ / mol . R stands for gas constant.

In addition, the curing temperature management device 101 may determine the predicted strength over time from the equivalent age using either Equation 3 or Equation 4 below. Specifically, through Equation 1

For example, the management temperature may be determined such that the greater the difference between the target strength and the current strength, the greater the difference from the current curing temperature.

Then, the curing temperature management device 101 transmits a control command generated according to the predicted strength to the maintenance control device 103 to control the curing temperature of the concrete.

Alternatively, the formwork can be demolded only when the current strength reaches 5Mpa 24 hours before the concrete is poured. If the concrete formwork is before demolding, the curing temperature management device 101 considers the time to reach the predicted strength (eg, 5Mpa) to generate an alarm when the time to reach the predicted strength is reached, or the current strength is the target You can set an alarm to occur when it becomes burglary.

The curing temperature management device 101 determines that an abnormality has occurred in the concrete when the collected curing temperature does not belong to a preset reference temperature range. Alternatively, the curing temperature management device 101 determines an abnormal temperature range in advance, and determines that an abnormality has occurred in concrete when the curing temperature belongs to the abnormal temperature range.

The curing temperature management device 101 may set a reference humidity range in advance, and determine that an abnormality has occurred in the concrete when the collected humidity does not belong to the reference humidity range. Alternatively, the curing temperature management device 101 may determine whether the concrete is abnormal by determining whether the result obtained by applying different weights to the collected curing temperatures or humidity and adding them together belongs to a preset ideal criterion.

In addition, the curing temperature management device 101 transmits an emergency notification to the user terminal 104 when an abnormality occurs in the recuperation control device 103 .

In step 305, the curing temperature management device 101 generates a control command in consideration of the detected abnormality when an abnormality is detected in the concrete. For example, the curing temperature management device 101 generates a control command to lower the curing temperature when the curing temperature is higher than the reference temperature range. Alternatively, the curing temperature management device 101 generates a control command to increase the curing temperature when the curing temperature is lower than the reference temperature range.

In step 306, the curing temperature management device 101 transmits the generated control command to the health control device 103. The maintenance control device 103 adjusts the curing temperature by controlling the cooler or the heat supply according to the received control command.

For example, when the control command is a command to increase the curing temperature, the recuperation control device 103 operates the heat supply to increase the curing temperature. Alternatively, when the control command is a command to lower the curing temperature, the maintenance control device 103 operates the cooler to lower the curing temperature.
