Gap-graded Aggregate - Civil Engineering Forum

Gap-graded aggregate concrete is difficult to pump because of the danger of segregation, and is not suited to slip-form paving. Fig. 2, confirms that using given materials with a fixed aggregate/cement ratio (but adjusting the fine aggregate content), approximately the same workability and strength are obtained with gap and continuous gradings.
