| Abstract | ||
| In recent years the demand for limestone as a building material, a base layer in roads construction and a raw material in cement manufacture in Egypt has markedly increased. It becomes therefore a national need not only to satisfy the requirements of this material but also, to orient these rocks to the optimum uses "techno-economic". The optimum utility of any limestone deposit determined according to the physical and mechanical properties, which is used rating and weight to determine the quality index for each deposit site. The quality index depends on physical properties such as porosity, density and water absorption and mechanical properties such as compressive strength, tensile strength and coefficient of dynamic fragmentation. Rating of uses as building material, in road construction, and in cement manufacture are considered. All of these parameters are determined for three different locations for limestone quarries around Cairo (El Katameya-Ain El Sokhna road, 15th of May city, and Ber Gendary in Helwan), and four locations for dolomite quarries (Ataqa Cairo-Suez Road, El Saf, Wadi Garawi, and Wadi El Gebbu). The final result indicated that, all studied locations are suitable for using as building materials except El Saf site. | ||
