Design and evaluation of concrete for restoration interventions on Byzantine monuments

Abstract

Abstract The aim of this research is to design and produce concrete for the restoration of Byzantine monuments. Mixes with different binders, pozzolanic additions and aggregates were produced. The chemical (hydraulic products, consumption of Ca[OH]2), the physical characteristics (apparent density, porosity accessible to water through capillaries and capillary rise coefficient), the compressive and flexural strength, the static and dynamic modulus of elasticity were evaluated. From the obtained results, it is drawn that a light-weight concrete with low value of elasticity modulus was produced by mixing hydrated lime, artificial pozzolan (2.5% p.w.), ceramic fragments and sand. The chemical and the physico-mechanical characteristics of this concrete fit with the ones of the authentic concrete, ensuring the compatibility to building materials.
