摘要：Composite material nowadays has a competitive role in controlling other material. Therefore, coating other material using such composite material help to enhance the mechanical compressive and failure strength of deteriorates ancient materials Thebes limestone is attractive source for a lot of researcher. Natural weathering like rains, rockslides, moisture, salty groundwater absorption and changing temperature can damage or even may weaken the strength of such deteriorates ancient buildings. Compression Samples of ancient Thebes limestone are coated with Nano calcium carbonate and Nano Calcium Hydroxide. While single edge notch bending samples are treated cracked face using Nano calcium carbonate. The results showed an enhancement in both compression and fracture strength.
