Cement Grout an overview ScienceDirect Topics

Cement grouts are commonly used with water to cement ratios of about 0.5-4. At lower w:c ratios, the grout will tend to be more uniform, but also more difficult to inject due to high viscosity. Balanced stable cement grouts (commonly used in dam foundation grouting) may include a number of additives to generate a homogeneous balanced blend of water, cement, and additives to produce a product
