“…The achieved results are consistent with literature data [3,4,8,9]. Figure 3 and 4 are SEM micrographs of cement composites samples with 2.5wt.% alkali-resistant glass fibers stored 1460 days in 3% and 5% NH4NO3 solutions.…”

Abstract. The aim of the research program was a degradation of composites containing alkaliresistant glass fibres (ARGF) by ammonium nitrate solutions. The effect of 3 and 5% ammonium nitrate solutions and storage long time on physical properties and structure of cement composites is presented. Application of glass fibre had a positive effect on the properties of cement pastes, most notably, this was reflected on the compressive strength and transverse tensile strength. Despite the positive effects but also the application of fiberglass there was a significant loss of strength cement mortars exposed to prolonged exposure to ammonium nitrate solutions.

“…Corrosion and materials degradation have a deleterious effect on the resilience of the RCS, and even further when SCC develops, as they reduce the service lifetime and its capability to withstand external damage [3]. The corrosion damage on RCSs presents direct consequences on the sustainability, where the shorter lifespans caused by premature failure require demolition and rebuilding [4,5].…”

Herein, the stress corrosion cracking (SCC) susceptibility of duplex (UNS S32205) and austenitic (UNS S31653) stainless steel (SS) reinforcements was evaluated using integrity assessment criteria. Mechanical properties were analyzed and compared by different SCC susceptibility factors. The integrity assessment was conducted applying Cosenza, Creazza, and Ortega ductility criteria, following three different standards (ACI 318-19, ASTM A615, and FIB). A conventional carbon steel (UNS G10080) reinforcement was also evaluated for comparative purposes, whose high residual stress value (>280 MPa) promoted a high corrosion growth rate. Duplex UNS S32205 SS grade showed a significant decrease in elongation, leading to failure after ductility assessment at high chloride concentrations. Fractographic analysis of both SS grades, duplex and austenitic, revealed less than 40% brittle areas at 8 wt.% Cl−, while UNS G10080 had over 85% at 4 wt.% Cl−.
