RAZON POZZOMIX is generated by incineration of pulverised coal; which is collected by means of an equipment known as electrostatic precipitators. RAZON POZZOMIX is consumed by the ocnstruction industry for many applications due to its efficacy as a reactive pozzolanic material. This property makes it favourable for use as a replacement of OPC in multitude of applications encompassing concretes of various grades and performances, factory prepared ready to use mortars, factory prepared grouts and factory prepared concrete articles
- Use of RAZON POZZOMIX ensures
- Improved workability of the mortars / concretes
- Improved waterproof characteristics in the concretes/ mortars
- Reduced shrinkage in plastic state of concretes/ mortars,
- improved cohesion of the concretes/ mortars
- Reduced aggression of sulfate attack,
- Higher impermeability and thus better performance in RCPT &
- Lower heat of hydration in concretes
Typical test characteristics of RAZON POZZOMIX are as below:-

Recommended replacement of cement by POZZOMIX is upto 30% in most concretes, wherein it is observed that there is a profound improvement in the qualities and performance of concrete. This makes the concrete very ideal for most applications like-
- Site batched concrete (grades upto C-60)
- Ready mix concrete (of grades upto C-60)
- Self compacting concrete
- Pre cost concrete.
- Mass concrete pours etc.
It has been observed that upto 40% replacement of cement by utilising RAZON POZZOMIX has been successfully used for various applications, including preparations of-
- Masonry mortars, General purpose mortars
- Factory prepared Grouts for anchors.
- Factory prepared Ready mix plasters, and tile glue
- Preparation of Portland pozzolonic cement
- Foam concrete or areated concrete etc etc…
POZZOMIX is of great value in manufacture of factory prepared construction articles like concrete benches, pavers & concrete blocks, AAC blocks etc,
In arid climates, and tropical climates like the African continent, addition of RAZON POZZOMIX aids in lowering heat of hydration, which is essential for mass concrete structures like huge foundations, dams, huge footings etc. It ensures a monolithic concrete structure by mitigating micro – cracks in the concrete matrix.
Over the past decades, sucessfully RAZON POZZOMIX has been a boon to construction projects – be it residential / commercial tower projects or massive infrastructure projects which are the pride of any country. RAZON POZZOMIX has been a sucessful partner to cement inprojects like construction of
- Highways .
- Power plants and so on.
Across the globe, RAZON POZZOMIX Is supplied in easy to use bags of 20/30/40 kg capacity OR we can supply POZZOMIX in 1.4 MT jumbo bags. POZZOMIX is always supplied on containers load basis.
Technically, 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 concretes achieve and surpass the necessary target strenght at 28 days age, and thus it is very safe to say that Fly ash additions does not affect ultimate strengths of concretes.
At many projects we have supplied an liquid additive “RAZON ACC 313”. RAZON ACC 313 is considered the latest of generation strength accelerator for concretes because its addition increases the 24 hours, 3 day & 7 day strength substantially. By its addition the early strenghts are comparable to and higher than mixes made of plain cement concrete. It is observed that ACC 313 is capable of providing upto 70-90% of concrete strenght within 72 hours of placing the concrete. Dosage of ACC 313 is 200 ml / 50 kg cement. It is generally added to the concrete at the batching plant. It does not affect (accelerate/ retard) the setting time of concretes.
The pH of Razon AAC 313 is near neutral, free of chlorides and nitrates. RAZON ACC 313 is safe for use in steel embedded concretes.
