Abstract

The research aims at an archaeological and technical study of the brick merlons bearing decorations in the Islamic archaeological buildings in Cairo. Also, the manufacturing material was dealt with (wage), manufacturing methods and stages, and an experimental study was conducted that dealt with the comparison between several materials that were used in their different concentrations, which are 3%, 1%, in order to reach the best materials and concentrations with high efficiency in resisting moisture It also gives good results through industrial aging tests using several methods, including exposing the samples to acidic water spray, then spraying the samples from all sides with sulfuric acid diluted by 5%, then placed in a drying oven at a temperature of 45 °C for 8 hours. This process has been repeated for three consecutive cycles. Exposing the samples to the effect of saline solutions, and the samples were immersed in a solution of sodium chloride salt with a concentration of 25% for 4 hours, then the samples were dried in an oven at a temperature of 45 °C for 8 hours, then the samples were left at room temperature for 12 hours. The samples were dried in an oven. Drying at a temperature of 105°C for 24 hours, then immersed in water, after that it was placed in a drying oven at 65°C for 8 hours, then exposed Dry to heat at the same temperature and the same period, and it is dry. Finally, it was cooled at room temperature for 16 hours.
