Neat Cement Grout

Definition

Neat cement grout is a fluid mixture composed solely of hydraulic cement and water, with or without admixtures. It can also refer to the hardened form of this mixture.

Purpose

Neat cement grout is used in construction for filling voids, sealing joints, and securing structural elements. It provides a strong, dense, and durable material that enhances the structural integrity of various construction components.

Examples of Use

• Grouting Foundations: Used to fill voids and cracks in foundations to improve stability and load-bearing capacity.
• Sealing Joints: Applied in masonry to seal joints between blocks or bricks, preventing water infiltration.
• Post-Tensioning: Utilized in post-tensioning tendons in concrete structures to protect against corrosion and provide additional strength.

Related Terms

• Hydraulic Cement: Cement that sets and hardens through a chemical reaction with water and is capable of doing so under water.
• Admixture: A material added to cement or concrete to modify its properties.
• Grout: A fluid form of concrete used to fill gaps or reinforce existing structures.

Notes

• Mix Ratio: The proportion of water to cement in neat cement grout is critical for achieving the desired consistency and strength.
• Applications: It is often used in repair and restoration projects due to its ability to fill small voids and cracks effectively.
