Maha Cement PSC is 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 Loesche GmBH, 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) but also steep particle size distribution (PDS) which helps Maha Cement achieve high early strength and excellent durability properties in concrete.
The advantages of using Maha Portland Slag Cement (PSC)
Maha Cement is best for all types of constructions. It is especially recommended in regions where the structure is exposed to harsh environmental condition.
Low Heat of Hydration – most suitable for mass concrete work
Maximum resistance to alkalis and sulphates attack
Progressive increase in strength over the years
Smooth Surface finish – no surface cracks
Ideal for both concreting and plastering
Improved workability and consistency
Higher strength and high durability
Higher resistance to corrosion
