Use of blended cements, especially pozzolanic cements, in the construction of concrete dams is generally considered as an effective measure for minimizing the risk of deleterious AAR expansion, thanks to the ability of their hydration products to incorporate most of the alkalis initially available in the pore solution of the cementitious matrix [9, 10].

These materials were first produced on a significant scale by Purdon in the 1940s (Purdon 1940), but the worldwide awareness of this technology started to develop in 1950s with the work developed by Glukhovsky in Eastern Europe, who investigated the binders used in ancient Roman and Egyptian structures (Glukhovsky 1994), discovering the possibility of producing binders using low basic calcium or calcium-free aluminosilicates (clays) and solutions containing alkali metals (Glukhovsky 1959).
