| description | A detailed Limestone from the Samana Suk Formation in Dhamtaur, Pakistan, was studied to assess its potential as a construction aggregate. The limestone contains variable amounts of dolomite, which can be harmful to concrete. Petrographic analysis and ACR tests showed that the dolomite content is low and the limestone has low alkali reactivity. Engineering laboratory tests confirmed that the limestone meetsASTM and AASHTO standards for aggregate properties. Therefore, the limestone from Dhamtaur can be used as an aggregate in concrete and asphalt works. The results of the engineering laboratory tests indicate that limestone from the Samana Suk Formation, located in the Dhamtaur area, exhibits specific gravity (2.84g/cm3), water absorption (0.0781%), Los Angeles abrasion value (20%), and sulfate soundness (2.23%). These findings strongly support the viability of utilizing these rocks as aggregate, aligning with the established standards of ASTM and AASHTO. A petrographic examination indicates the presence of dolomite in a minor proportion (2-15%) with a Porphyrotopic-S type texture. Analysis of ACR results demonstrates a slight expansion in the limestone (0-0.01%), implying low reactivity to alkali. Consequently, it is reasonable to propose the utilization of these rocks as a source of aggregate in concrete and asphalt projects. |
