Maha – Portland Slag Cement (PSC), conforming to the IS 455-1989, is manufactured from high quality clinker and superior quality granulated blast furnace slag. The slag used contains more than 95% glass content – the most desired parameter to manufacture PSC. The unique feature of our Grinding Units used for manufacturing this cement is the Vertical Roller Mills (VRM) – the most modern technology imported from LoescheGmBH, Germany. The clinker and slag are separately ground to reach high fineness level and then blended in a high efficiency mechanical blender. This has not only enabled us to achieve high fineness (Blaine 3700+ cm2/g) in our Maha Cement but also steep particle size distribution (PDS) which helps Maha Cement achieve high early strength and excellent durability properties in concrete
