What is lean concrete & where it is used - we civil engineers

Lean concrete is a mix where the amount of cement is lower than the amount of liquid present in the strata.. The higher the Aggregate/cement ratio, the leaner the concrete. In lean concrete, less quantity of paste is available for providing lubrication, per unit surface of aggregate and hence the mobility of aggregate is restricted .
