Lime based concrete and mortar enhanced with pozzolanic materials – State of art

Analysis of the Rheological Properties of Natural Hydraulic Lime-Based Suspensions for Sustainable Construction and Heritage Conservation

“…The quality and chemical composition of lime vary across different regions, emphasizing the importance of an initial study of its physical and chemical properties before its use in construction and restoration [31]. Natural hydraulic lime (NHL-5), natural volcanic pozzolan (NVP), and metakaolin (MK) were the powder materials used.…”

Overview of the challenges and current solutions in organic and hybrid coatings for historical monuments and architecture

“…115 Historically, a wide variety of pozzolana were used including ash, clay, silica, alumina, and organic matter. [116][117][118] The incorporation of lime clasts, volcanic ash, sand, and quicklime through a hot mixing process is believed to have resulted in the self-healing properties of Roman Concrete. 119 Recent studies have focused on the development or improvement of lime materials through the use of new pozzolanic binders, including maize straw ash, 115 fly ash, fumed silica, and rice hull ash.…”

“…119 Recent studies have focused on the development or improvement of lime materials through the use of new pozzolanic binders, including maize straw ash, 115 fly ash, fumed silica, and rice hull ash. 117 Work by Yang et al successfully utilized sludge waste products from drinking water purification processes as a pozzolan, after thermal treatment, due to its high aluminiumand silicon-based material content. 120 Lime materials have been utilized historically and research will only continue to increase their performance in the future.…”
