Quick Summary

An alkoxysilane is a type of silane compound that contains an alkoxy radical. Silanes are compounds made up of only silicon and hydrogen, with the general formula Si_nH_{2n + 2}. Alkoxysilanes are sometimes used as sealants for concrete structures.12

The broader category of silanes includes compounds where hydrogen atoms are replaced by other groups. These compounds are generally less stable than their hydrocarbon counterparts and can react vigorously with air or alkaline solutions. Alkoxysilanes are a part of sol-gel chemistry and have been explored for strengthening and repairing stone.12

…similar manner, the application of alkoxy silanes in recent decades offers the conservator a method by which amorphous silica can be introduced as a binder and strengthener for deteriorated sandstone. Some silanes will also impart water repellency to the stone. Synthetic polymer-based consolidants include acrylic polymers, epoxies, and polyesters. Although…
