Additionally, the curing box includes an internal temperature sensor and an external temperature sensor which provide data to a control module. The control module permits adjustment of the fluid temperature within the box. The present disclosure additionally provides a method for curing a specimen in the curing box. The method compares the temperature signal from the external sensor to the internal sensor and adjusts the temperature of the fluid in the box to match the temperature reported by the external sensor. Additionally, the method controls the flow of a second fluid into the box thereby circulating the first fluid to substantially eliminate temperature stratification of the first fluid in the box. Thus, the method provides a controlled environment for curing the specimen.
