Why sand is used in concrete?
The strength of the concrete is inversely proportional to the water/cement ratio. In other words, the more water you use to mix the concrete, the weaker the concrete mix. The sand and the aggregate help to reduce the cost and also limit the amount of shrinking that happens to the concrete as it cures.
