Concrete should be designed to achieve workability, durability, and strength, in the most economical manner. Concrete mix design is the process of selecting suitable constituent materials and determining their optimum proportions to produce concrete that meets your specified performance requirements.

Due to the natural variability of materials and their properties, it is often not possible to determine the exact mix proportions solely through theoretical or computer-based calculations. Therefore, laboratory testing and experimental data play an important role in developing and validating an appropriate concrete mix.

Concrete mix design process can be tailored to achieve a wide range of strength grades, from M10 to M100, depending on the project requirements. Selecting the appropriate mix requires a thorough understanding of concrete properties, material characteristics, and relevant experimental data. The primary objective of a design mix process is to produce good-quality concrete that meets the required performance criteria while optimising the use of materials and minimising overall cost.

Good quality concrete imparts:

• Better strength
• Better durability
• Dense and homogeneous concrete

Economical cement consumption ensures:

• Up to 15% of cement can be saved for M20 grade concrete by using design mix process
• Optimal use of available materials

Types of services for mix designs include:

• Abrasion resistance
• Abrasion value
• Accelerated cube strength
• Air content and alkali content
• Bleeding test
• Block density
• Bridge load test
• Compressive strength
• Core cutting
• Permeability test
• Rapid chloride penetration test (RCPT)
