Freezing and Thawing Hysteresis Effects in Experimental Analysis of Frost Deicing Salt Resistance of Cementitious Materials

摘要

Hysteresis effects are very frequent in experimental studies of porous building material. In the case of frost deicing salt resistance, hysteresis effects between freezing and thawing were reported in calorimetric and expansion experiments. They often were explained by a difference in the active pore diameter.
