Unless otherwise required, what should be the slump consistency of mixed grout?

The recommended slump consistency for mixed grout, unless otherwise specified, should be between 8 and 11. This range is important because it ensures that the grout possesses sufficient fluidity to flow into joints and voids, achieving proper bonding and filling capabilities. A slump within this range typically indicates that the grout is workable, which is crucial for achieving optimal performance in applications such as masonry or tile setting.

Using grout with a slump consistency that aligns with these specifications also helps in preventing issues such as segregation of materials or the inability to fill gaps effectively. In construction practices, adhering to the proper slump ensures that the grout will achieve the required strength and durability once cured, promoting long-lasting results in the finished structure.
