Advanced Methods of Concrete Mixture Design

Modern advances in mix design methods have built upon the necessity of maximum density gradation, using the concept of ‘particle packing’. This concept talks about the optimization of the granular skeleton of the concrete mix to obtain the best packing density.

BRE Concrete mix design method

A popular simplified mix design method is that from BRE. Compressive strength is, in general, related to durability. The greater the strength the more durable the concrete. To satisfy the required compressive strength, a value for water/cement (w/c) ratio is estimated for an appropriate test age (generally 28 days) and cement type.
