ASTM C476 delineates cementitious grouts into four types, each with a specific mixing ratio. Two types are made with self consolidating formulations which do not require mechanical processes for settling, but which are relatively new to the industry and less commonly used. The other two types are considered conventional grouts, and require vibration or other mechanical application to settle the grout into place after pouring. Conventional grouts can be made with fine aggregates only (a fine grout), or with a mixture of fine and coarse aggregates (coarse grout). This CP reviews a mixture of fine and coarse aggregates (coarse grout), which is suggested to be the more cost effective option and is typically mixed on site, but may also be available in pre-blended preparations, or as a ready-mix.
