Effectiveness of a new nanostructured consolidant on the biocalcarenite from Agrigento Temples Valley.

A study of the effectiveness of a crack-free consolidant nanomaterial and a nanostructured consolidant with hydrophobic properties, developed in University of Cadiz was carried out for a biocalcareous stone from Agrigento (Italy). The products were obtained by a silica oligomer in presence of a surfactant and, in the hydrophobic product,with the addition of PDMS. The purposes of the research were increasing hydrophobicity and consolidation of the stone. The tests effectuated demonstrated the desired characteristics improved
