Aggregates- Sand could be the fantastic combination. Gravel or crushed stone is the coarse aggregate for most mixes.

Improvements in gradation might also have an impact on workability in the concrete, Despite the fact that a wide range of gradation can be utilized for numerous programs.[73][74] An unwanted gradation can signify using a huge mixture that is definitely as well substantial for the scale in the formwork, or that has far too couple scaled-down combination grades to serve to fill the gaps between the bigger grades, or working with way too tiny or an excessive amount of sand for a similar cause, or working with much too minor water, or an excessive amount cement, or simply using jagged crushed stone rather than smoother spherical mixture for example pebbles.
