  • CEMENT CONCRETE MIX DESIGN

    4. Maximum nominal size of aggregate In general, larger the maximum size of aggregate, smaller is the cement requirement for a particular watercement ratio, because the workability of concrete increases with increase in maximum size of the aggregate. However, the compressive strength tends to increase with the decrease in size of aggregate.
