  • Effective material age estimation device, compressive strength estimation device, and program
    Publication number: 20230258621
    Abstract: Provided is an effective material age estimation device capable of appropriately taking relative humidity variation into consideration when estimating an effective material age. This effective material age estimation device comprises a temperature term calculation unit 13 for calculating a temperature term ?T dependent on the temperature of cast concrete, a humidity term calculation unit 14 for calculating a humidity term ?RH dependent on the relative humidity of the concrete, and an effective material age calculation unit 15 for calculating the effective material age of the concrete by summing products of the temperature term ?T, the humidity term, and a step time term ?ti. The humidity term ?RH is introduced, and the sum of the products is weighted using the term.
