RADIOGRAPHIC STUDIES OF THE STRUCTURE OF POLYMER-IMPREGNATED CONCRETE

The structure of polymer impregnated concrete and its cracking behavior under load was studied by radiographic technique. It was observed that polymer impregnation not only reduced the porosity of the mortar but also of the interface. No microcracks were observed at the polymer-impregnated contact phase, on loading, in contradistinction to ordinary concrete. Cracks, which were first detected around 70-80 percent of the ultimate load, propagated usually through the aggregate, instead of following its boundary. Dispersion and orientation of fibers had a significant influence on the cracking behavior. Distortion and kinking of fibers indicated very good adhesion between the fibers and the polymer-impregnated matrix. /ACI/
