Abstract
The aim of this paper is to make an initial evaluation of chloride-induced corrosion behaviour of steel in alkali-activated fly ash and compare it to behaviour of classical cement mortar. Fly ash used in this research was obtained from regional production and was activated with sodium silicate and sodium hydroxide. Setup for evaluating corrosion behaviour consisted of structural steel plate covered with mortar layer under tap water or simulated seawater solutions. Corrosion behaviour of structural steel plates was monitored by Open Circuit Potential (OCP) and Linear Polarization (LP). The mortars have been additionally characterized by their mechanical properties, pore structure obtained by mercury intrusion porosimetry (MIP), electrical resistivity and chloride migration according to NT BUILD 492.
