flaky crush in aggregate

  • Evaluation of the quality of fine materials and filler ...

    2014-9-30 · Thus for flaky particles, larger amounts of finer material is needed to achieve a good workability. A common practice in mix design, when the coarse aggregate is flaky, is to increase the amount of fine aggregate. If the smaller particles are also flaky, more materials are needed in the finer fractions. This holds true down to the finest particles.
