This work reports the design, development, and operation of a hot plate device with a guard called HD20 Hot Box to evaluate, under steady-state conditions, the transfer of heat by conduction through test tubes with prism-shaped faces. Parallel, and indirectly determine the thermal conductivity of construction concretes with different aggregates. IRAM 11559, IRAM 11549, and IRAM 11601 standards valid in Argentina were applied for its design. The hot box consists of two central units: the heating and cooling units. The thermal conductivity values obtained with this apparatus agree with those published in the literature.
