Alkoxysilanes, low-viscosity monomers capable of polymerizing into the porous network of stone by a sol-gel process, are widely used as consolidants in the restoration of stone monuments. However, since consolidation is a non-reversible application capable of causing serious harmful side effects to the original material, stone consolidation is almost always considered a very risky intervention. Alkoxysilanes are insoluble in water, so co-solvented systems are very often used, but even knowing… 
Effect of solvent type on polycondensation of TEOS catalyzed by DBTL as used for stone consolidation
We have investigated the effect of solvent in the sol–gel process of tetraethylorthosilicate (TEOS) when di-n-butyltin dilaurate (DBTL) is used as polycondensation catalyst. Two sets of materials
TEOS–colloidal silica–PDMS‐OH hybrid formulation used for stone consolidation
The consolidation of materials concept, which consists of introducing a chemical substance (consolidant) into degraded stone, has been applied to architectural conservation. Silicon compounds such as
TEOS/PDMS-OH hybrid material for the consolidation of damaged pottery
The use of organic–inorganic hybrid compounds containing tetraethoxysilane (TEOS) and hydroxyl-terminated polydimethylsiloxane (PDMS-OH) is one of the most promising approaches for using

Effects of Adding Nanosilica on Performance of Ethylsilicat (TEOS) as Consolidation and Protection Materials for Highly Porous Artistic Stone
Historical sandstone surfaces and architectural heritage may undergo unwanted changes due to the exposure to many mechanical, physical and chemical deterioration factors. This paper evaluates the
Solvent effects on structural properties of SiO2 gel using n-octylamine as a catalyst
We have investigated the effect of solvent(ethanol, acetone, isopropanol) on the sol–gel process of tetraethylorthosilicate (TEOS) in which case, n-octylamine is used as polycondensation catalyst.
New nanomaterials for consolidating stone.
A novel sol-gel synthesis, in which a surfactant acts to make the pore size of the gel network more coarse and uniform, is shown to provide an effective alternative for the consolidation of stone.
Sol–Gel derived hybrid materials for conservation of fossils
Abstract Fossils are nonrenewable natural heritages formed by Mother Nature. After being excavated or exposed, fossils can be destroyed by weathering and water erosion. However, until now, there is

Stress During Drying of Two Stone Consolidants Applied in Monumental Conservation
The object of this paper is to evaluate behaviour during drying of two stone consolidants: Wacker OH and Tegovakon V, containing tetraethoxysilane. During drying, the gel network contracts due to
Acidic Sol−Gel Polymerization of TEOS: Effect of Solution Composition on Cyclization and Bimolecular Condensation Rates
For batch sol−gel polymerization of TEOS in acidic ethanol solutions, we report kinetic trends over a wide range of initial solution compositions that yield homogeneous gels. We find in these systems

TLDR
A clearer picture of the nature of the bonding to the surface is obtained by combining the low-frequency data with the spectral information for the hydroxyl region, and the spectra are complicated by the reaction of methanol with the surface.
