Economic Evaluation of Building Stones of Sindh
Abstract
Large deposits of good quality building stones of Precambrian to Miocene age are exposed in different parts of Sindh. Study of geotechnical properties of these rocks including compressive and shear strength, soundness and porosity show compatible values to the recommended ASTM range. In addition to the above parameters reserve estimation, accessibility, availability of labour and geographical controls have also been considered in the economic evaluation of these deposits. Optimum benefits from these deposits can only be achieved if materials are used according to their suitability, i.e. as building stones, grinding/miling stones, decorative stones or as raw material for cement, glass and steel industries.
