Effect of Petrographical Characteristics on the Engineering Properties of Some Egyptian Ornamental Stones [ READ ]
M. A. Abd El– Hamid, W.M. Draz, A.F. Ismael, M. A. Gouda. And S.M. Sleem
Ornamental stones have wide variety in their mineralogical, petrographic and engineering properties.Five different types of Egyptian orna-mental stones have been chosen to be analyzed chemically and petro-graphically for studying their engineering properties as a function of their petrographic characteristics. These types of studied ornamental stones including;Aswan red granite,Aswan granodiorite (grey granite), Minya, Red Sea and South Sinai compactlimestone (marble like) were prepared for mechanical and physical tests. The mechanical and physical properties included; uniaxial compression, abrasion resistance, apparent porosity, water absorption, and dry density.The results indicated that the engineering properties of samples of the same type are generally a function of a wide range of petrographic parameters including; appearance,texture, grain size, mineralogical composition,degree of metamorphism, diagenesis, rate of strength minerals, pores, micro-cracks and fossils that may affect the stone selection for different uses.
