GENERAL USE

 It is in the class of blended cements according to TS 197-1: 2011 standard, it has a wide application area. It is especially preferred for pouring concrete in hot weather. Its workability is higher than Portland cement, it is suitable for general use.
It increases the quantity obtained in building chemical productions thanks to its low density and contributes to workability in ready-mixed concrete production. It provides long-term durability with its trass content.
It is released to the market as packaged and bulk cement.
