Sarooj
Sarooj is a traditional water-resistant mortar used in Iranian architecture,[1][2] used in the construction of bridges,[3] and ice pits or earth refrigerators (yakhchal).[4]
It is made of clay and limestone mixed in a six-to-four ratio to make a stiff mix, and kneaded for two days [citation needed]. 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.
