Compressive and Failure Strength of Sand Stone with Different Strengthen Materials

摘要

Composite materials have advantages of giving new properties for the component materials. Therefore fundamental of forming and fabrication of composites material has been used to enhance the mechanical compressive and failure strength of deteriorates ancient materials. Habu Temple has been often in the observing of a lot of scientific research. Natural weathering like rains, moisture, salty groundwater absorption and changing temperature can damage or even may weaken the strength of such deteriorates ancient buildings. Sandstones are of the main construction building materials of this ancient temple. Compressive strength of sandstones is affected by weathering conditions. Samples of ancient Nubian sandstones are coated with Paraloid 44 (B44), Paraloid 72 (B72), Ethyle silicate and Wacker (OH100). The results showed that in general, Mechanical Compressive strength of sandstone decreases due to salty groundwater action. Ethyle silicate coating material is more efficient and gives considerable protection about over 250% enhancement when the sample immersed in water gives a about over 140 % enhancement.
