  • nanoindentation and sem edx characterization of the geopolymer to steel Interfacial Transition Zone for a reactive porcelain enamel coating
    Composites Part B-engineering, 2015
    Co-Authors: P. G. Allison, A. J. Diaz, Charles A. Weiss, O. G. Rivera, Robert D Moser, S. S. Holton
    Abstract:

    Abstract The increasing use of alternative cementitious materials such as geopolymers as an environmentally-friendly alternative to traditional cements requires an improved understanding of the Interfacial Transition Zone (ITZ) between the matrix and reinforcing steels. In this study, nanoindentation measurements were spatially coupled to images with scanning electron microscopy and chemical composition using energy dispersive X-ray microanalysis. The study focused on the microstructure and chemical composition of the Interfacial Transition Zone (ITZ) for reinforcing steel embedded in a geopolymer mortar. The ITZ was analyzed for uncoated steel and steel coated with a reactive porcelain enamel that improves bonding and corrosion resistance. Results indicate that a more gradual Transition of mechanical properties and chemical composition for the coated steel coupled with improved integration to the mortar correlates to increased bond strength measured in macroscale experiments.

  • effect of basic pumice on morphologic properties of Interfacial Transition Zone in load bearing lightweight semi lightweight concretes
    Construction and Building Materials, 2011
    Co-Authors: Mustafa Ayhan, Hatice Gönül, İsmail Ağa Gönül, Askeri Karakuş
    Abstract:

    Abstract The objective of this research is to determine the effect of basic pumice on morphologic properties of Interfacial Transition Zone in load-bearing lightweight/semi-lightweight concretes. In this respect, it has been researched how the chemical and physical structure and the volumetric ratio of basic pumice affected the following three morphologic properties of Interfacial Transition Zone: compactness, width and physical adherence. In accordance with the stated purpose, 15 concrete serials with various properties were produced using basic pumice as aggregate and 670 images were taken from the samples collected from these serials via scanning electron microscope (SEM). Semi-analytical detections were performed based on non-generalizing numeric data obtained in conclusion of the determination of grain limits in these images and comments on visual analysis. In accordance with these detections, it has been concluded that the basic pumice has a high level of potential to contribute to the morphologic properties of Interfacial Transition Zone.
