Change in Microporosity of Granitic Building Stones upon Consolidation Treatments
Publication: Journal of Materials in Civil Engineering
Volume 19, Issue 5
Abstract
The microporosity of granite stones has been studied in both the untreated condition as well as after being treated with a consolidation treatment using two commercial products. A decrease in the specific surface area and pore size distribution (especially micropores) has been found in samples treated with an organic silicate consolidant. Treatment with a consolidant containing polysiloxane (a water repellent agent) leads to variable results, depending on the precise pore structure of the untreated stone. The use of consolidation treatments may restrict flow of fluids (e.g., water, saline solutions, etc.) through the pores of the stones, which may decrease degradation.
