    Advanced Methods of Concrete Mixture Design

    Conventional mix design methods tend to use grading differently for coarse and fine aggregate. Typically, the available aggregates are proportioned in such a way that the grading of the combined aggregate is similar to a specific curve or lies in between given limits. These numbers or limits are typically obtained from maximum density

    Grading of Aggregates - Aggregate Grading | The

    In grading of aggregates, the voids in the mixed aggregate would be minimum when the sand is just sufficient to fill the voids in the coarse aggregate. Voids in the coarse aggregate are filled in by sand and voids in the sand are filled in by cement. Mix that occupies the least volume is the densest and will produce the best results.
