Three kinds of materials (organic silicon as the main component and the introduction of fluorocarbon compounds; mixture of 30% Remmers300 and 70% alcohol,the mixture of 30% silane monomer and 70% alcohol) were used to consolidate the stone samples, and then use mobile single sided NMR(nuclear magnetic resonance) technology to detect porosity, pore size distribution of samples at depth profiles of 0, 3, 5 mm. The results show that the porosity of samples and the water content were reduced after consolidation, the first and the third kind of consolidation materials penetrate better than the second. Through three dimensional morphology analysis, the third kind of consolidation material changes color and surface topography of the sample changes significantly. Comprehensive comparison shows that the first kind of consolidation material is more desirable.
