Why lean concrete is used?

Lean concrete serves the purpose of providing a uniform surface to the concrete foundation. This also helps to prevent the direct contact of the foundation concrete from the soil. This is a good choice to provide a flat bottom for a terrain that is uneven or dirty.

Does lean concrete have gravel?

Lean concrete does not contain many of the heavy, high-density rock and sand elements that are present in normal concrete. A mixture of standard concrete materials, reclaimed and crushed concrete, discarded sand, and recycled ash make lean concrete far less expensive and simple to make and use than standard concrete.
