| Abstract | ||
| Engineering and geological study for using sedimentary desert gravel in concrete production was performed, so as to provide resources for aggregate used in construction works, especially in desert regions. Hand specimens test in addition to examining of(24) slides showed that desert gravel consist mainly of Calcite mineral with deferent crystal sizes ,showing recrystalization and dolomitization . Some inclusions and fossils showing Calcite replacement where founded. Tests on aggregate and on concrete proved that good quality concrete can be obtained using desert gravel as coarse aggregate. The properties of this concrete were found to be nearly similar to those properties when river gravel was employed. Crushing of desert gravel enhanced properties especially its compressive and tensile strength. Long term exposure to humid environment did not indicate any deterioration due to alkali-aggregate reaction of concrete production using desert gravel. Similar results were noticed when river gravel used. | ||
