Neat Cement Paste

Definition

Neat cement paste is a mixture of hydraulic cement and water, in both its fluid state before setting and its hardened state after setting.

Purpose

Neat cement paste serves as the binding medium in concrete and mortar, providing the necessary adhesive properties to hold aggregates together. It is also used on its own for small-scale repairs and surface coatings.

Examples of Use

• Concrete Production: Acts as the binder in concrete, holding the aggregates together.
• Mortar: Used in mortar to bind bricks or stones in masonry construction.
• Surface Repairs: Applied directly to surfaces for patching cracks and small holes.

Related Terms

• Concrete: A composite material composed of coarse aggregate bonded together with a fluid cement that hardens over time.
• Mortar: A mixture of cement, sand, and water used to bind construction blocks together.
• Hydration: The chemical reaction between cement and water that causes the mixture to harden.

Notes

• Consistency: The water-to-cement ratio in neat cement paste affects its workability and strength.
• Setting Time: Proper curing is essential to achieve the desired hardness and durability.
