Alkali activation of fly ashes. Part 1: Effect of curing conditions on the carbonation of the reaction products

Abstract

This paper deals with the alkaline activation of fly ashes for the production of a novel cementitious material and with the previous termeffect of curing conditions on the nature of the reaction products. Curingnext term procedures favouring carbonation process negatively affects the development of mechanical strength of this new alkaline cement. Carbonation of the system involves its pH modification and consequently the modification of the nature of the reaction productsn and the kinetics of reactions.
