Abstract
This research was partially supported by Mining and Petroleum Engineering Department, Faculty of Engineering Al-Azhar University, Egypt, that provided machines to finish the research.
Highlights
The chemical composition of limestone is CaCO3, other form calcium subtitle magnesium to produce dolomite (CaMg (CaCO3))
There are many limestone deposits extended in all governorate in Egypt, which used in building stone, cement industry, highway construction as filling materials, concrete aggregate, etc. (Ahmad, El-Sageer, & Hussein, 1996)
El-Beblawy, El-Sageer, Abul, & Tawfik (2004) investigated some of property and specifications of Helwan rock samples: for conservation treatment of Ancient Egyptian limestone monuments Said (1981, 2017), rock strength carried out by Duroscope rebound values with all consolidates which up strength of the tested sample
Summary
In this paper using physical and mechanical properties to evaluate the Egyptian limestone according to the relationship between their properties especially the degree of water saturation. Samples were obtained from six different locations (Helwan, Minia, Assuit, Qena, Sohag, and Aswan). The strong correlation between porosity and density, and good correlations between uniaxial strength and tensile strength. Applying the fitting curve technique to check the best correlation between the different property of limestone to identify the best relationship to apply the prediction to find the limestone property in other location as regards applying conditions. Results carried out that the strong correlation between porosity and density, and good correlations between uniaxial strength and tensile strength as summarize in the outcome of data interpretation. In terms of their hydric behavior and mechanical properties, are the index for the suitability of using limestone
