Proper experimental knowledge about the porosity and water absorption capacity of a coarse aggregate is
required as its affects the durability of concrete because of:
I. Freezing and thawing
II. Reaction with chemically reactive fluids
III. Increasing the workability of concrete
Porosity and water absorption capacity of coarse aggregate affects the durability of concrete because of:
(i) Freezing and thawing
(ii) Reaction with chemically active fluid
(iii) Increasing the workability of concrete
