..., foundational literature and recent experimental, analytical, and field studies are synthesised to critically assess major chemical grout families, including sodium silicate, colloidal silica, acrylate-based systems, polyurethane grouts, and resin-based grouts. Emphasis is placed on the relationships between...

... some of the geotechnical hazards that involve the subsoil of Napoli, mostly made in its upper part of collapsible, unsaturated pyroclastic silty sands (pozzolana). This paper refers to the results obtained by treating pozzolana with sodium silicate solutions of water and a small percentage of silicates...

... with a watersoluble two-component epoxy resin is investigated. The experiments were carried out using either epoxy resin only («one-shot process’), or in combination with sodium silicate (‘two-shot process’). For this reason, two epoxy resin solutions were employed. One was thick, with a water/ resin (W/R) ratio of 1...
