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.
