RAZON POZZOMIX is obtained by incineration of pulverised coal; collected by means of an electrostatic precipitators. RAZON POZZOMIX is used because it is one of the most efficient pozzolanic materials, which allows it to be used as a replacement of OPC in multitude of applications including but not limited to factory prepared ready to use mortars/ grouts and most concrete applications,
- Additions of RAZON POZZOMIX provide
- Enhanced workability in the concretes/ mortars
- Enhanced waterproof characteristics,
- Very lower to ‘zero’ plastic shrinkage,
- Enhanced cohesiveness in the concretes/ mortars
- Reduced possibilities of sulfate attack,
- Enhanced impermeability and thus better results in RCPT &
- Lower heat of hydration in concretes, this prevents micro-cracks in the concrete matrix !
Typical test characteristics of RAZON POZZOMIX are as below:-

By making replacement of cement by POZZOMIX of upto 30% in most concretes, it is observed that a simultaneous improvement in the performance of concrete is obtained for most applications like-
- Site batched / In – situ concrete (of grades upto C-60)
- Pre cost concrete.
- Self compacting concrete
- Ready mix concrete (of grades upto C-60)
- Mass concrete pours
Upto 40% replacement of cement by incorporating use of RAZON POZZOMIX has proved a consistent success for varied applications like in preparations of-
- Factory prepared Ready mix plasters, and tile glue
- Preparation of Portland pozzolonic cement
- Foam concrete or areated concrete
- Factory prepared Grouts for anchors.
- Masonry mortars, General purpose mortars etc etc…
Apart from these mainstream applications, POZZOMIX is of great importance in manufacture of pavers & bricks, AAC blocks.
Addition of RAZON POZZOMIX aids in lowering heat of hydration, especiialy beneficial for mass concrete structures like dams, huge foundations etc. What it does is it helps in preventing micro – cracks in the concrete matrix, thus ensuring a monolithic concrete structure.
Sucessfully RAZON POZZOMIX has been a boon in construction of various projects including but not limited to residential / commercial tower projects & infrastructure projects which define the strenght of a country, like-
- Highways .
- Power plants
- Ports and so on.
RAZON POZZOMIX Is supplied bags of 20/30/40 kg capacity alternatively we can supply POZZOMIX in 1.4 MT jumbo bags. POZZOMIX is always supplied on containers load basis.
Generally, replacement of cement by fly ash in concrete lowers the early strengths (3rd day 7th day) as compared to plain cement concretes. However it must be noted that these concrete achieve target strenght at 28 days age, and thus are very safe to say that Fly ash additions does not affect ultimate strengths of concretes.
If you require, we can provide you with an additive “RAZON ACC 313”. The addition of ACC 313 improves 24 hours, 3 day & 7 day strength substantially. The early strenghts are comparable to and higher than mixes made of plain cement concrete. By addition of ACC 313 to the concrete upto 70-90% of concrete strenght can be obtained within 72 hours of placing the concrete. ACC 313 is used at a dosage of 200 ml / 50 kg cementatious material and it is added to the concrete at the batching plant. It does not alter(accelerate/ retard) the setting time of concretes.
The pH of Razon AAC 313 is approx neutral, free of chlorides and nitrates. RAZON ACC 313 is safe for use in steel embedded concretes. RAZON ACC 313 is considered the latest of generation strength accelerator for concretes.
