Highly Pozzolanic Ultrafine Siliceous Fly Ash for use in High performance concrete
For advice on mix proportion contact
Pozzocrete 100 is being manufactured at the Dirk Pozzocrete plant at Nashik. 90 % of the particles of this product are below   The high silica content and sum of oxides (SiO2 + Al2O3 + Fe2O3) are similar to what would be expected for a Class F Fly Ash as per EN 450 or ASTM C 618 designation.  This makes Pozzocrete 100 a substitute of silica fume in concrete whilst showing further advantages in durability, workability, sulphate and chloride resistance. Pozzocrete 100 reduces the heat of hydration in concrete. 

Advanatges:
The Ultrafine Fly Ash branded as  Pozzocrete 100 can produce  concrete strength comparable with that produced with a highly reactive pozzolan such as Silica Fume (SF). To reach the performance levels of SF concrete at early age, generally the concentration of UFFA and SF are the same must be slightly and the total water in the concrete must be reduced by about 15-20 %.
Pozzocrete 100 displays a strong tendency to reduce water demand. For comparable workability as SF concrete, a 15-20% reduction in total water content, together with as much as a 30% reduction in HRWR (=High Range Water Reducer), is possible;
Pozzocrete 100 concrete also displays a lower tendency towards cracking due to drying and autogenous shrinkage compared with SF concrete;
Processing FA into an ultra-fine material like Pozzocrete 100 with a refined particle size distribution clearly improves its performance as a durability-enhancing admixture. The practical significance of the increased reactivity, from a concrete technology perspective , is that a given improvement in performance canbe achieved at a lower level of replacement (that is, the ultra-fine material is more efficient) compared with an unprocessed FA and at an earlier age. As such, Pozzocrete 100 offers a viable alternative to SF in certain applications.

Quality assured siliceous Fly Ash for used in concrete and other cement applications 
Pozzocrete 60 is a high efficiency pozzolanic material, obtained by selection and processing of power station fly ashes resulting from the combustion of pulverized bituminous coal. Pozzocrete 60 is subjected to strict quality control.
Pozzocrete (P60)a processed quality assured fly ash, investigated for its use as a partial replacement for cement in cement mortar (1:3). The utilization of Pozzocrete (P60) as cement replacement material in mortar or as additive in cement introduces many benefits from economical, technical and environmental points of view. This paper presents the results of the cement mortar of mix proportion 1:3 in which cement is partially replaced with Pozzocrete (P60) as 0%, 10%, 30%and 50% by weight of cement. Four set of mixture proportions were made. First were control mix (without Pozzocrete (P60) with regional fine aggregate (sand)) and the other mixes contained Pozzocrete (P60) obtained from DIRK India Private Limited, nashik, Maharashtra state. The compressive strength has been obtained with partial replacement of Pozzocrete (P60) with cement. Test results indicate the decreases in the strength properties of mortar with Pozzocrete (P40, P60 and P100) for strength at 28 days as partial replacement with the cement in the cement mortar 1:3. So it can be used in non-structural elements with the low range compressive strength where strength is not required and low cost temporary structure is prepared.
