Class C Fly Ash - Oil Well Cementing Grade

Pozzolan-cement blend feed for lightweight, thermally stable well cement slurries.

Pozzolan-cement systems let an operator cut slurry density without losing compressive strength, and they hold up far better than neat cement under downhole temperature. This grade is supplied to a tightened particle size and chemistry band so the slurry behaves the same from one batch to the next.

Thickening time and rheology are confirmed against the operator programme before dispatch.
