Abstract
Abstract An improvement in a process for the impregnation of masonry with an alcoholic or benzine solution of an alkyltrialkoxysilane or a partial condensation product thereof which improvement involves including in the alcoholic or benzine solution an organofunctional silane having a basic organo group or an alcoholate of an element selected from the group consisting of silicon, a metal of the First Main Group of the Periodic System, a metal of the Second Main Group of the Periodic System, a metal of the Fourth Sub-Group of the Periodic System, and a metal of the Fifth Sub-Group of the Periodic System; an improved composition for the impregnation of masonry comprising a mixture of an alkyltrialkoxysilane or a partial condensation product thereof and an organofunctional silane having a basic organo group or an alcoholate of an element selected from the group silicon, a metal of the First Main Group of the Periodic System, a metal of the Second Main Group, a metal of the Fourth Sub-Group of the Periodic System and a metal of the Fifth Sub-Group of the Periodic System.
