What is lean concrete ? - eigenplus

Lean concrete is a type of concrete in which the amount of cement is less , i.e less than 10 % of the total volume of concrete. In this type of concrete the aggregate to cement ratio is large and the cement to water ratio is low, thus the cement paste available to ensure good bonding between different ingredients of concrete is also less.
