Abstract
:
ABSTRACT: The aim of the project was to determine whether there is a correlation between colour changes recognized in digital image processing and the deterioration properties shown by the limestones used in the ancient monuments of Cairo. 12 samples of limestone extracted from ancient quarries around Cairo known to be the principal sources of the monument stones were selected for analysis. A comparative study was then made between the fresh sample state, before being subjected to by any environmental changes, and the final state after being exposed to a rapid chemical weathering procedure, designed to resemble exposure to a long period of poor environmental conditions. The aim was determine whether a relationship exists between deterioration in the color spectrum shown by the samples and deterioration in their physical and mechanical properties.. This will provide a method for using deterioration in color system by digital photography to predict quantitatively the deterioration in physical and mechanical rock properties and thus predicting precisely degree and method of remedial treatment needed for the stonework. The results obtained indicated that percentage of color deterioration is very closely related to deterioration of porosity (R2 = 1 ), then to deterioration of compressive strength ( R2 = 0.9 ) then to density ( R2 = 0.8 ).
