GENERAL USE

 		 According to TS 197-1:2011 standard, it consists solely of Portland cement clinker and gypsum plus minor additional components. It is suitable for general usage. It is suitable for use in situations where early mould removal is required (prefabricated practices) It is preferred for pouring concrete in cold weather.
It provides high early and ultimate strength in ready-mixed concrete production. It enables production with its high hydration heat property in cold weather.
It is marketed as packed and bulk cement.
