DISPOSITIVO PER LA DETERMINAZIONE DEL TEMPO DI INDURIMENTO DI MATERIALI LEGANTI E TERRE PER ANIME

The device comprises a container (4) for the test specimen (5), said container being placed inside a heating furnace (1) provided with a cap (2) and being mounted on a table (3) fixed to the cap (2) of the furnace (1). Electrodes (7) and (8) are located inside the container (4) and are electrically connected through a circuit to a recording instrument for measuring electrophysical parameters between the electrodes (7) and (8), which are connected to each other so that a sealed chamber (9) is formed therebetween. The device comprises as well a guiding stand (10) placed outside the furnace (1) and provided with a cantilever (11) fixed to the cap (2) of the furnace (1) and movable along the stand (10) with the possibility of its fixation and thus providing for a precise setting of the table (3) with the container (4) inside the furnace (1). The device further comprises a mechanism (12) for feeding a gaseous catalyst into the sealed chamber (9) between the electrodes (7) and (8), said mechanism consisting of a pipe (13) connected to a tank (14) for the gaseous catalyst. The guiding stand (10) is provided with a hollow (39) housing inside it the pipe (13) for feeding the gaseous catalyst to the sealed chamber (9) between the electrodes (7) and (8) and electrical wires (40) connecting the electrodes (7) and (8) to the circuit for measuring electrophysical parameters between the electrodes (7) and (8).
