    Answer: Aggregate is gap-graded when intermediate sizes are essentially absent from the gradation curve. Usual gap-graded mixes contain aggregate retained on a 3/4- or 1 1/4-inch sieve, and particles passing the No. 4 sieve. Gap-graded mixes are used to obtain uniform textures for exposed-aggregate concrete and can also increase strength and .

  • Gap-graded Aggregate - Civil Engineering Forum

    Gap grading can then be defined as a grading in which one or more intermediate size fractions are omitted. The term continuously graded is used to describe conventional grading when it is necessary to distinguish it from gap grading. On a grading curve, gap grading is represented by a horizontal line over the range of sizes omitted.
