abstract = {Ethyl silicate (tetraethoxysilane, TEOS) is commonly used for consolidating construction materials containing
siliceous components such as sandstone, cement mortars and concrete structures. This is especially due to its high
compatibility with the substrates´ silicate matrix. Its lack of bonding to calcareous substrates is however
considered an important handicap. Here we investigate the consolidation effectiveness and durability of a
combined TEOS-nanolime treatment applied on weathered biocalcarenite stone. We report evidence of physical
and chemical interactions between the two consolidant materials resulting in limited drying shrinkage and the
formation of calcium silicate hydrate (C-S-H) gel, responsible for improving the treated carbonate substrate
mechanical properties and treatment durability as compared to both products used separately. The results of this
experimental study are promising and could be the foundation for further studies toward obtaining a compatible,
effective, and long-lasting consolidation treatment for porous calcareous building materials.},
