What is the difference between no-fines concrete, lightweight concrete and lean concrete?

Pervious concrete is sometimes called “no fines” concrete. It is designed with high porosity and allows water to pass though. It is commonly used in concrete pavement so as to reduce surface runoff and allow the recharging of ground water. The high porosity is achieved by a network of interconnected void. “No fines” concrete has little or no fines and contains just enough cement paste to cover the surface of coarse aggregates while maintaining the interconnectivity of voids.

Lightweight concrete is characterized by low density (1,400kg/m3 to 1,800 kg/m3) and is made of lightweight coarse aggregates. In some cases, even the fine aggregates are also lightweight too. The primary use of lightweight concrete is to reduce the dead load of concrete structures.


Lean concrete, which is also known as cement bound material, has low cementitious material content. It has low concrete strength and is commonly used as roadbase material.

This question is taken from book named – A Closer Look at Prevailing Civil Engineering Practice – What, Why and How by Vincent T. H. CHU.
