Many of the important and commonly observed properties of hardened concrete are related to the quantity and characteristics of the various types of pores in the paste and aggregates within the concrete. The engineering properties of concrete, such as strength, durability, shrinkage, and permeability, are influenced or controlled by the pores in the concrete and the relative amounts of the different types of pores. It is therefore not surprising that tests of various properties depending on porosity, such as permeability and absorption, are frequently applied to concrete.
