fluid loss additive for cement

Chemical Additives for Oil Well Cementing Open Access

Fluid loss control agents are used to minimize fluid loss by creating filter cake of cement slurry on the surface of the formation. Fluid loss control additives reduces the filtration of the fluid by increasing the viscosity of the slurry and decreasing the permeability of the filter cake thereby protecting water

3 Ways to Reinforce Concrete wikiHow

Feb 23, 2019Concrete naturally loses water over time, which causes it to shrink and thus become weaker. Pour shrinkage-reducing admixture into your concrete, per the manufacturer's instructions, to prevent cracking or curling caused by this water loss. You can purchase shrinking-reducing additives at any store that sells concrete mixtures.

Any fluid loss from the fluid system during the transitional period causes a corresponding loss in hydrostatic pressure. This pressure loss can be substan-tial enough to cause complete loss of overbalance pressure. Flu-id loss additives limit the rate and volume of fluid loss from the cement slurry, thereby limiting the hydrostatic pressure losses
