Geotechnical assessment of limestone and dolomite quarries around cairo for different purposes

Abstract EN

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 orption 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.
