| Popis: | This research aims to test the Suitability of Sandstone rocks taken from Injana formation in the Al-Shirqat region (Northern Iraq), as cladding stones for riverbank protection, where the Injana formation in addition to the quaternary sediments are mainly exposed in the study area. For this purpose, three stations were chosen representing the exposed study area where sandstone layers are located. Petro-physical examinations and mechanical geotechnical investigation are undertaken. The Petro-physical examinations showed that the absorption rate ranges between (1.13 - 1.16) %, and the dry density ranges between (1.75 - 1.82) g/cm3, while the Specific gravity ranged between (2.59 - 2.64). The mechanical properties results showed that the values of uniaxial compressive strength ranges between (7.97 - 12.28) MPa and mechanical abrasion (82.3 - 89.2) %, and the values of chemical abrasion ranged between (8.7-12.3) %. By comparing these properties with the National Center for Construction Laboratories and Research standards (NCCLR), It was found that they were within the limits of the standard except for the values of mechanical abrasion, it falls outside the specifications. Also, according to Florida Department of Transportation Standards (FDOT) that compared with, the properties of sandstone rocks are not suitable for cladding purposes because the property of mechanical abrasion falls outside the limits of the standard, and when comparing the properties of the Sandstone with American standards (ASTM), It turned out to be within the limits of the specification. |
