MPA : Mechanical properties of alkali-activated concrete

As the chemical composition of alkali-activated concrete differs from that of conventional concrete, and also differs substantially from one mixture to another because of different precursors and alkaline solutions used, the bond behavior, the strength gain and time dependent properties in conventional concrete and alkali-activated concrete are not the same.
