P100

P100 is a Ultrafine processed fly ash designed for producing High Performance Concrete (HPC) with high early and 28 days strength, highly improved workability and high durability. It is a potential microsilica replacement and can be used in dosages of 5 to 8% in HPC. It is obtained by careful selection through mechanical air-classification of coal fired thermal power station ash.

Physical specifications:

• Retention on 45 microns: 0%

• Retention on 25 microns: max 0.25%

• Specific surface area: min 625 m2/kg

• Bulk weight: 0.65 tons/m3

• Particle shape: Spherical

Salient Features of P100

1) 100% passing through 45 micron and 0.25% retained on 25 micron.

2) Specific surface area minimum 625 m2/kg.

3) Water Reduction 10-12% less as compared with OPC mix in Standard Mortar and 15-20% less in CONCRETE.

4) Gives workable mix at water cement ratio as low as 0.22 at comparatively lesser admixture dosage.

5) RCPT Value or Coulomb value at par with micro silica mix. 6) Higher early strength as compared to Silica fume mix.

7) Substantial 24 hours or One day strength.

8) High performance concrete can be produced at much lower cost as compared with silica fume mix as price of Pozzocrete® 100 is less than 1/3rd of silica fume and on the top of it admixture dosage can be reduced by at least 0.2% which is substantial saving in case of PC based admixture
