Durability of alkali-activated binders: A clear advantage over Portland cement or an unproven issue?

► This paper questions the durability of alkali-activated binders. ► Special attention is given to the case of efflorescences. ► The durability of alkali-activated binders is conditioned by the use of calcium. The alkali activation of alumino-silicate materials is a complex chemical process evolving...
