16.	Chemical deterioration of Egyptian limestone affected by saline water I
Salt forms are aggressive deterioration problems, which occur on all stone surfaces, mortars and renderings through saline solutions transferred to the stone pores. Deterioration of Egyptian limestone is primarily due to water-soluble salts. The formation of these salts on calcareous stone is the most important chemical reaction involving saline water to cause stone degradation. The study explains the different deterioration ... إقراء المزيد
