Free water in cement slurry: Why is it critical?

Free water is a standard lab test done for cement slurries (described in detail in API RP 10B). It is basically mixing the cement slurry, then let it sit for two hrs before measuring the percentage of free water - basically the visually, almost clear water on top of the slurry. The test can be carried out either at room temperature vertically ...

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.
