VICKSBURG, Miss., CHAMPAIGN, Ill. -- Researchers with ERDC’s Geotechnical and Structures Laboratory (GSL) and Construction Engineering Research Laboratory (CERL) were recently notified that their paper on reactive porcelain enamel coating had been accepted for the Journal of Construction and Building Materials.
The paper, "Nanomechanical and chemical characterization of the interface between concrete, glass-ceramic bonding enamel and reinforcing steel," authored by Drs. Paul Allison, Robert Moser, Charles Weiss Jr. and Philip Malone of GSL and Sean Morefield of CERL reports their research results from a detailed study of the microstructure of an ERDC-developed reactive porcelain enamel coating for concrete reinforcing steel.
This coating system has been shown to significantly increase the bond strength of reinforcing steel with concrete. The study provided new insights into the mechanical and chemical interactions between the coating and cement-based materials using a technique to spatially correlate nanoindentation measurements with site specific chemical composition and micrographs obtained with scanning electron microscopy.
Results of this research will help guide the optimization of these technologies for developing the next generation of reactive porcelain enamel coating systems to improve the bond between reinforcing steel and concrete.
