Concrete mix design determines the ideal proportion of cement, sand, aggregates, and water to achieve the required strength and durability. In Nepal, proper mix design is essential for sustainable construction under varying climate and site conditions.

Common Concrete Grades

• M10 (1:3:6): Used for non-structural works like levelling and PCC.
• M15 (1:2:4): Suitable for footing and flooring.
• M20 (1:1.5:3): For beams, slabs, and reinforced members.
• M25 and above: Used for bridges, columns, and heavy-duty structures.

Key Factors Affecting Mix Design

• Water–cement ratio and workability
• Aggregate size and gradation
• Climate and curing conditions
• Strength requirement and durability target
