Sarooj is a traditional water-resistant mortar used in Iranian architecture,[1][2] used in the construction of bridges[3] and yakhchāl, ancient Persian ice houses.[4] It is made of clay and limestone mixed in a six-to-four ratio to make a stiff mix, and kneaded for three days.[citation needed] A portion of furnace slags from baths is 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.
Its origin (in Persian: Saru) is lime, i.e. limestone mixed with arsenic.[5]
History
[edit]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.[3] The Sheikh's biogas bath-house in Isfahan featured a water-impermeable sarooj composed of lime, egg white, and bamboo dust.[2]
Another alternative formulation used for yakhchāl and water tanks in Iran uses "sand, clay, egg whites, lime, goat hair, and ash in specific proportions."[4] All of these examples utilize pozzolanic properties and/or incorporate biopolymerization to increase the durability and impermeability of the plaster.[6]
Soak the soil for at least two weeks with water. The water should be free of impurities and suitable for drinking.[7]
