Abstract

The rocks used in the study represent mostly strata of carbonate rocks and some argillitic and igneous and metamorphic rocks which are currently quarried in Southern and South East Ontario and widely used in the concrete industry. The tests were conducted on rock cores two centimetres in diameter and 4.5 centimetres high. In the first series of tests, physical properties such as water adsorption, 24 hour water saturation, vacuum saturation and rate of water absorption were determined. In the second series of tests dry cores, cores with adsorbed water and fully saturated cores were subjected to microwave energy in a standard microwave oven and the amount of absorbed heat was measured. In the third series of tests, the fully saturated samples were exposed to low temperature (${-}16\sp\circ$C) and the amount of frozen pore water was determined by calorimetric means. Length change on freezing was also recorded. In the last, the fourth series of tests, changes in physical properties were determined by repeating the tests for vacuum saturation and water adsorption on specimens subjected earlier to wetting, freezing, and thawing.
