Cement Grout

Definition

Cement grout is a cementitious mixture of Portland cement, sand or other ingredients, and water, forming a uniform paste used to fill joints and cavities between masonry units.

Purpose

The purpose of cement grout is to provide structural stability, seal gaps, and prevent water infiltration in masonry constructions. It ensures the integrity and durability of the structure.

Examples of Use

1. Tiling: Filling the spaces between tiles to secure them in place.
2. Masonry Walls: Filling cavities and joints in brick or stone walls.
3. Underpinning: Stabilizing foundations by filling voids and strengthening weak soil.

Related Terms

• Mortar: Similar to grout but generally used for bonding bricks and stones together.
• Portland Cement: The primary component of cement grout, known for its strong binding properties.
• Hydraulic Cement: Cement that hardens upon contact with water, used in various grouting applications.

Notes

• Proper mixing and application are critical to the effectiveness of cement grout.
• Grout can be colored to match or contrast with the masonry units.
