Nanotechnology and construction: use of nanoindentation measurements to predict macroscale elastic properties of high strength cementitious composites

Abstract: This paper aims to present the experimental results involving the use of nanoindentation measurements and prediction of macroscale elastic properties of high performance cementitious composites (HPCC). The elastic properties of HPCC mixture were evaluated at different length scales by nanoindentation (microscale), and elastic moduli and compressive strength tests (macroscale). The nanoindentation results, obtained by grid indentation with subsequent phase deconvolution, were complemented by an independent poro… Show more

“…Multiscale materials can be considered homogeneous or heterogeneous depending on the level of observation. According to Silva et al [1], cementitious composites are considered as typical representatives of multiscale materials since they can be treated as homogeneous at the macroscopic level (length scale cm ~ m) and as heterogeneous materials at a more precise level of observation (scale in length nm ~ cm).…”
