BG-60L (Gas Block Additive)

Product Information

BG-60L

Description

BG-60L is a liquid suspension of silica fume which is composed of ultrafine amorphous (non-crystalline) spheres of silicon dioxide. The large surface area (>20 cm2/g) and high content of amorphous silicon dioxide (> 90% SiO2) give BG-60L superior pozzolanic properties, therefore excellent fluid loss and anti gas migration properties. Typical addition 1.5 – 3.0 gal per sack cement.

Advantages

  • Minimum free water and lower viscosity.
  • Low permeability and low fluid loss.
  • High compressive strength and early strength development.
  • Useful for lightweight systems to 11ppg.
