Concrete paving slabs were tested to achieve the following three objectives: (1) assess the degree of freeze-thaw durability required in the various climatic regions of Canada, (2) assess the merit of standard testing methods, and (3) evaluate the ad

Water held in the pores of a solid becomes unstable when cooled to temperatures below 0 degrees C. If the conditions permit, the water leaves the pores and ice accumulates outside the system. In case of high cooling rate, high degree of saturation, a

Length changes of mortar-porcelain and mortar-quarry tile composites (typically 10x3x8mm) have been examined in the temperature range -10 to +50 degrees C. The effect of heating rate (1 and 4 degrees C/min.), dimensions of specimens, volume ratio of

Dimensional changes of porous 96% silica glass have been determined during exposure to aqueous NaOH solution. Depending on the thickness of the specimen (1, 3, 4, or 8 mm) and the concentration of the alkali (0.1, 0.4, 0.8, 1.6, 3.2 and 6.4 M), eithe

The dimensional changes and the thermograms of cement specimens were determined during temperature cycles (+5 degrees to -60 degrees C, 0.33 degrees C/min). In each case, freezing processes at -8 degrees and -40 degrees C and melting processes at -11

An earlier theory of frost action is further developed and its implications considered, particularly with regard to testing. Factors determining durability of paste, dimensions of sample, degree of saturation and rate of cooling are discussed. It is
