When mixing grout, unless otherwise required, what is the acceptable slump range?

The correct answer is 8 to 11 inches for grout slump range, which is generally acceptable unless specific project requirements state otherwise. Grout is a mixture used in construction to fill gaps or to support tiles, and the slump test measures the consistency and workability of this mixture.

A slump of 8 to 11 inches denotes a relatively fluid mixture, which is essential for ensuring the grout can flow into and fill the spaces between tiles or bricks effectively. This range allows for a good balance between workability and strength, ensuring that the grout can adequately adhere and create a strong bond once it cures.

Understanding the importance of slump also ties into practical applications on job sites, where excessively thick mixtures can lead to application challenges and underly the importance of following recommended standards to achieve optimal durability and aesthetics in the finished product.
