The purpose of the study was to investigate the relationships between properties of rock and the corresponding mortars under different environmental conditions as determined by compressive stress testing. The mortars were prepared with different type of aggregates but the same proportions of water, cement and aggregate. The rock aggregates were mostly carbonate rocks (limestone and dolomite). The mortar blocks were cured for 28 days. Three cores were drilled from each mortar block. The cores were first tested for water adsorption and absorption. Then, a series of compressive tests, up to 6.9 MPa (1000 psi), were performed on the mortar cores. The compressive tests were carried out under seven different environmental conditions: room (ambient) relative humidity (about 40% RE) and 98% RH, saturated in water, and saturated in 3% NaCl solution. All the tests were done at room temperatures (about 21°C) and freezing temperature (-20°C). The mortar data so obtained were then combined with the rock aggregate test results from previous studies, which included compressive tests (under same conditions), adsorption, absorption and magnesium sulphate loss.
