  abstract     = {{The valorization of waste material for building applications has a long and successful
history. Nowadays, byproducts such as fly ash, ground-granulated blast furnace slag
(GGBFS), and silica fume are usual constituents of cement and concrete. These supplementary
cementitious materials (SCMs) are recognized for enhancing certain properties
of concrete, while also reducing its environmental impact. The huge amount of
cement consumed globally demands additional sources of SCMs. A number of waste
materials are prospective candidates, and reports on almost any type of waste being
used in cementitious materials can be found in the present literature. The comprehensive
study of their capabilities should comprise their ecological, economic, and engineering
benefits. This chapter focuses on the effect of alternative SCMs from wastes
on the transport properties of concrete.
Transport properties are important for durability and performance in the service life
of concrete structures. The most usually assessed transport properties are water
transport (permeability, sorptivity, and absorption), gas permeability (oxygen and
air), carbonation, ion transport (chloride penetration and lixiviation), and electrical
resistivity. Although they are connected, there are specific features to observe for each
case. The effect of SCMs on transport properties mainly depends on the chemical and
physical modifications that they cause in the microstructure. Some properties are more
affected by chemical changes, whereas others are more affected by physical changes.
The analysis of transport properties in cementitious materials with waste used as
SCMs allows developing the most convenient cementitious systems containing them.
Alternative sources of SCMs are numerous; therefore a comprehensive analysis of all
of them is rather difficult. This chapter offers a review of a limited number of types of
waste that have been tested as SCMs in cement, mortar, and concrete. Byproducts that
are already extensively used in the market (e.g., fly ash,GGBFS, limestone powder, and
silica fume) are not included in this review. The selected materials are not necessarily
the ones that demonstrate the most convenient technical or commercial features but the
ones with which the authors have more experience. Some of the comments in this chapter are certainly applicable to other types of SCMs, so the content may still be
valuable for readers interested in other types of SCMs not included in this section.}},
