Specific Surface Area - an overview | ScienceDirect Topics SSA, defined as the total surface area of a solid material per unit of mass, is an important feature for sorption processes. SSA is dependent on the size of the particles, as well as on the structure and porosity of the material. The concrete structure is porous; however, the concrete powder was characterized by rather low SSA.
