FROST ACTION IN CEMENT-STABILIZED COLLIERY SHALE

This paper describes a laboratory investigation of frost action in cement-stabilized colliery shales in which their performance is evaluated in terms of the heave developed during prolonged freezing. Tests of nine unburnt and four burnt shales showed that the addition of cement reduced heave, except in the case of some fine-grained unburnt shales. These results are discussed in relation to the effect of cement on pore size, on permeability, and on strength. Of the strength tests undertaken, only the direct tensile test provided data that could be related to the behavior observed during a freezing test. Significant heave occurred only when the heaving pressure generated at the freezing front was greater than the tensile strength. It is concluded that freezing behavior is consistent with an energy balance between the work done in heaving and the energy liberated by supercooled freezing.
