Abstract: The objective of this paper was to evaluate the alkali-silica reactivity (ASR) and alkali-carbonate reactivity (ACR) of the 14 aggregate groups quarried from different locations. In order to serve the stated purpose, the investigated aggregate groups were tested in determining their alkali-silica reactivity using the ASTM C 1260 at the ages of 2, 4, and 8 weeks, and the modified ASTM C 1293 (prisms submerged in the 1N NaOH at 80°C) at the test durations of 4, 8 and 13 weeks. The aggregate prone to the alkali-carbonate reactivity was accessed using the ASTM C 1105 at the ages of 3, 6 and 12 months. The study revealed that the aggregates susceptible to alkali-carbonate reactivity were also shown to be reactive due to the alkali-silica reactivity.
