A NEW TECHNIQUE FOR DETERMINING THE DEPTH OF PENETRATION OF CONSOLIDANTS INTO LIMESTONE USING IODINE VAPOR
RAKESH KUMAR, & WILLIAM S. GINELL
ABSTRACT—In evaluating the effectiveness of consolidants for limestone, difficulty is encountered in the determination of the depth of penetration of consolidants. A simple procedure using iodine vapor for visualizing penetration depth is described. The technique is compared with other methods, such as fluorescent dye indicators, elemental analysis, scanning electron microscopy (SEM) observation, charring in an inert atmosphere, and acid etching, for effectiveness, applicability, and suitability.
