EFFECTS OF SATURATED AND UNSATURATED STATES ON THERMAL DIFFUSIVITY IN PERMEABLE CONCRETE

Abstract

This research examine permeable concrete under conditions of gap water saturation in cold areas, and investigate the effects of saturated and unsaturated states on thermal conductivity. This research revealed that thermal conductivity in permeable concrete is nearly the same as in normal concrete, and a linear relation is between void ratio for thermal conductivity. Furthermore, duration of the melting point by influence of the latent heat was confirmed by the temperature measured successively between low temperature and ordinary temperature, and a linear relation is between void ratio for duration of the melting point.
