Due to economic reasons, natural stones (armourstone) are very frequently used for the constructions of the breakwaters. Considering the functions of the stones at different zones of the breakwaters, various sizes with variable properties of the armourstones are used in breakwaters. Deterioration of armourstones with time in the form of abrasion and disintegration may end up with the damage of the engineering structures. Therefore, it is necessary to investigate the long-term performance and quality of the armourstones, which should be sound and durable. In this thesis, the properties of four limestones taken from two quarries with a known site performances as armourstones in Mersin and Kumkuyu harbors are studied .The site performances and durability of the limestones are compared with the field measurements and laboratory works.
