Concrete Mix Design

Concrete Mix Design is a method for selecting suitable ingredients of concrete and analyzing their relative quantities for producing concrete. The concrete produced should be made as economic as possible with minimum properties, significant workability, durability and strength. An accurate determination of mix proportions by using computer data is usually not possible as the materials used are essentially variable and their properties are not assessable quantitatively.
Concrete Mix Design is an extremely flexible building material which can be exclusive designed for strength that may range from M10 to M100. A mix selection needs appropriate knowledge of concrete properties as well as the experimental data and the most importantly, who conducts the mix design. The objective of preparing a design mix is to achieve a good quality concrete in the best economic way.

Good quality concrete imparts:

• Better strength
• Better durability
• Dense & homogeneous concrete

Economy in consumption of cement:

• Up to 15% of cement can be saved for M20 grade of concrete by suing design mix
• Best use of the available materials can be done

Some of the tests facilities for Mix Designs include:

• Abrasion resistance
• Abrasion value
• Accelerated cube strength
• Air content & alkali content
• Bleeding test
• Block density
• Bridge load test
• Compressive strength
• Core cutting
• Permeability test
• Rapid Chloride Penetration Test (RCPT)
