What is Porosity and Absorption in Aggregates about?

The porosity, permeability and absorption of aggregates influence properties of both fresh and hardened concrete like bonding, resistance to freezing and thawing, chemical stability, abrasion resistance, and specific gravity. The amount and rate of water penetration depends on pore size, continuity and total volume. When designing concrete mixes, the saturated surface dry (SSD) moisture condition of aggregates is used as a reference since it represents equilibrium where aggregates will neither absorb nor re
