SEVEN RINGS SPECIAL is a Portland Composite Cement (PCC). This type of cement is mainly designed and used to improve durability of concrete. It is manufactured by inter-grinding three major mineral components (MIC) – Pulverized Fuel Ash (PFA), Blast Furnace Slag and Limestone with common raw materials, Clinker and Gypsum.

This type of cement has been used in developed countries for the past few decades. The famous PETRONAS Twin tower in Malaysia and today’s The Burj Khalifa Tower (160 floors, 828m) in Dubai are few examples of structures built with composite cement.
