Since decades, pulverised coal is incinerated at power plants to provide fine fly ash, which is collected by electrostatic precipitators, it is further graded and selected specially for the construction industry, and supplied under the brand RAZON POZZOMIX. This product has sucessfully proved that it is one of the most reliable & effective pozzolanic material for substituting a % of cement in concretes and factory prepared ready to use glues, grouts and mortars etc.
- Adding POZZOMIX ensures
- Much Better workability of mortars & concretes
- Better densities and Waterproof characteristics,
- Practically zero plastic shrinkage,
- Lower water contents in the mixes
- Better cohesiveness
- Resistance to aggressive sulfate attack,
- Higher impermeability leading to better results in RCPT
- and Lower heat of hydration is which is most crucial in our arid climates of middle east countries like Saudi Arabia, Qatar, UAE and Yemen.
Upto 30% replacement of cement can be done by incorporating RAZON POZZOMIX, thus improving the quality and performance characteristics of the properties of concretes for all applications like-
- Mass concrete pours
- Ready mix concrete (grades upto M-60)
- Site batched / In – situ concretes (grades upto M-60)
- Mixes of Pre cast concrete.
- Mixes of Self compacting concrete
In many industries, it is the norm to add POZZOMIX as a cement replacement of 40%, depending the application, for eg in the preparations of formulations of :
- General purpose mortars for construction activities
- Preparation of Portland pozzolonic cement
- Formulations of ready to use Grouts for anchors, tile glue and so on…
- Ready plasters, and AAC block glue
- Foam/ Areated concrete mixes Etc…
Other than these mainstream applications, POZZOMIX is used substantially in the manufacture of concrete articles like concrete poles, concrete pavers & cement bricks, concrete tables & benches, AAC blocks and so on…

In the middle east region climates the environment is dry and sweltering, which is not good for humans let alone concretes; here RAZON POZZOMIX’s functionality is ideal because it lowers the heat of hydration of concrete, thus preventing micro – cracks in the concrete matrix while in hydration sage.
Truly ove the last decades, POZZOMIX is a boon – in all major residential / commercial tower projects & infrastructure projects where RAZON POZZOMIX has provided consistent results and super quality, like in the construction of
- Highways & Pavements .
- Ports & jetties,
- Tunnels (underground and underwater)
- Power plants and so on.

For so many decades we have been supplying POZZOMIX in easy to uss bags of 20/30/40 kg capacity, however we are poised to supply in 1.4 MT jumbo bags. POZZOMIX is dispatched in containers load basis.
Technically ,addition of fly ash to concrete as a replacement of cement does not affect ultimate strengths of concretes, however early strengths (3rd day 7th day) are slightly lower.
To improve early strength of concretes, RAZON has successfully developed an additive RAZON ACC 313, which increases the hardening characteristics of concretes, thus providing higher strenghts on 3rd and 7th day (comparable to and much higher than plain cement concrete strenghts). At a few projects we have experienced that a dosage of 200 ml / 50 kg cementatious provided a strength of 70-90% of the design strength on the 3rd day itself. RAZON ACC 313 does not affect (accelerate or retard) the setting of concretes
Razon AAC 313 is safe for use in concretes containing steel reinforcements. Its pH is approx 8 & it is deviod of chlorides and nitrates. It is the latest of generation strength accelerator for concretes.
