Importance of Gravel and Sand for Concrete Hunker

Apr 12, 2018  Smaller gravel particles equals a "fine" grade of concrete. Use the fine aggregate for concrete slabs or other smooth surfaces. A "coarse" aggregate means using larger pieces of gravel. Coarse concrete is helpful for sturdier projects. Concrete with a coarse aggregate doesn't produce a smooth look or feel but is stronger than a finer grade.
