Cement slurry design testing - PetroWiki

The primary reason for this is the low concentration of additives used in the slurry or set cement. This concentration in set cement can be even lower than that of the original slurry, if the additive is consumed and/or modified during the cement hydration reaction. The content of samples taken from downhole is often questionable in that it is ...

How to Make Concrete Slurry | Hunker

The ideal texture of concrete slurry is thick and pasty with a consistency similar to tempera paint. If the slurry is too runny or too thick, it will not adequately adhere to the concrete surface and will prevent bonding between the concrete layers. The ratio for a basic concrete slurry mix is 1 or 2 parts Portland cement to 1 part water.
