500 years old bridge in Langarud, Gilan, Iran/پل خشتی لنگرود گیلان

Kheshti bridge is located in Langarud, Gilan, Iran. It has 500 years old and has been restored four times. Kheshti bridge connected the Feshkali and Rahposhte neighborhoods. Kheshti bridge was made with brick and sarooj about 500 years ago. Sarooj in wikipedia: It's a traditional water-resistant mortar used in Iranian architecture, used in the construction of bridges, and ice pits or earth refrigerators. It is made of clay and limestone mixed in a six-to-four ratio to make a stiff mix, and kneaded for two days. A portion of furnace slags from baths are combined with cattail (Typha) fibers, egg, and straw, and fixed, then beaten with a wooden stick for even mixing. Egg whites can be used as a water reducer as needed. Mosaddad et al report the use of a mixture consisting of lime, sand and ash in the construction of an 1800 year-old Sasanian bridge-dam on the Karoon river south of Shooshtar. The Sheikh's biogas bath-house in Isphahan featured a water-impermeable sarooj composed of lime, egg white, and bamboo dust. Another alternative formulation used for yakchal and water tanks in Iran uses "sand, clay, egg whites, lime, goat hair, and ash in specific proportions." All of these examples utilize pozzolanic properties and/or incorporate biopolymerization to increase the durability and impermeability of the plaster.
