Lean Mix Concrete- Specifications and Uses of lean mix ...

Lean mix concrete is a mix in which the amount of cement present in the strata is lower than that of liquid. This is used as a base layer where other types of concrete are placed on the top. Concrete with more water content is known as lean because of a lower concentration of cement compared to other kinds of paving and building materials of ...

What Is a Lean Concrete Mix and How Is It Made?

Mar 29, 2021  As already mentioned, the cement content is low with a lean concrete mix. Also, you use fine aggregate in a lean concrete mix. This is typically made from recycled concrete pavement, discarded sand, or recycled ash. This is the material of choice over heavy and high-density rocks and sand. As a result, this makes for a cheap and easy-to-make mix.
