Consolidation of volcanic tuffs with TEOS and TMOS: a systematic study

Abstract In this study, nine volcanic tuffs from Armenia, Germany and Mexico were treated with two commercially available consolidants on base of silicic acid ester, as well different pretreatments an anti-swelling agent and/or primer components. Prior to the treatment, analyzed regarding their petrography mineralogy, a greater focus clay mineral content. The effect consolidation was evaluated by comparative analyses petrophysical properties weathering behavior before after treatments. main goals study identify general suitability consolidating treatments for types tuff, evaluating tartaric component tuff pursue approach finding molecular answer apparent problematics, testing smaller molecule sizes than current products market: tetramethoxysilane (TMOS).
