摘要

This chapter addresses the consolidation of silicate-based building materials such as adobe, mud brick, mosaic soil, cob, and others, by exploring the pozzolanic reaction between silica and calcium hydroxide nanoparticles, which may favor the in-situ formation of calcium silicate hydrate (CSH). The contribution reports on the characterization of the investigated systems and their application on mud-brick mock-up samples to demonstrate the consolidation effect. A significant case-study, where a floor mosaic soil required consolidation, is also reported. The comparison with other traditional products used to this purpose clearly show the potential impact of this new formulation.
