Fluid Loss Control Additives
Super absorbent polymers (SAPs) such as sodium polyacrylate can be used to modify the flow properties of the cement and to control fluid loss, thus decreasing the permeability of the cement. SAPs can increase the compressive strength of the cement.
Poly Vinyl Alcohol (PVA) powder is a non-retarding low temperature fluid loss/gas migration additive in light weight cement slurries that improves adhesion, flexural strength, workability and water retention of the cementing system. Bisley supplies PVAs that are easily dispersed in water and form stable emulsions.
