* Cement bowl: This is the most literal translation, referring to a bowl made of cement.
* Concrete basin: This is a more formal translation, and emphasizes that the bowl is made from a hardened mixture of cement, sand, and gravel.
* Cement mortar: This is less common but could be used if the "chatti" is referring to a small amount of cement mixed with water and sand, used as a mortar for building.
To understand the exact meaning, you'd need more context. Is it referring to a specific object or a concept?
For example, if you saw the phrase in a context discussing construction, it likely refers to a concrete basin used for mixing mortar or holding water.
