  • What are the Different Gravel Sizes? (with pictures)

    Oct 20, 2019· The smallest of all gravel sizes is usually size #10, which is also commonly known as screenings gravel. This gravel is typically around 1/8th of an inch (0.32 centimeters) in diameter, making it similar in appearance to coarse sand. Often, screenings gravel is used as the base for bricks, paving stones, and other similar items. In some cases

  • 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.
