Advantages
Properties
How it works :
Pozzolanic effect: It increases the performance of concrete & mortar formation. It acts physically to optimize particle packing of concrete or mortar mixture and chemically as a high reactive pozzolan.
Micro filler effect :
It is an extremely fine material, with an average diameter much finer than the cement. It gets well distributed in the cementations paste, thus blocking the bleed – water channels.
Packaging :
Available in 25 kg Plastic Bag or Jumbo Bag (1000 kg).
Quality :
Micro Silica is a super pozzolan – a finely powdered material which when added to cementitious matter increase durability and gives higher strength. It complies with ASTM C1240.
