Mechanical Properties of Cementitious Materials at Microscale

Abstract

In recent years, the advanced techniques have provided powerful tools for characterizing materials at micro- and nanoscales. This chapter reviews the developing history, test principle, parameter setting, and data analysis of a few techniques for measuring the microstructures and the small-scale mechanical properties of cementitious materials, including NI/MI, SPM, nanoscratch, SEM, X-ray CT, and MIP techniques. The instrumented indentation techniques can measure the mechanical properties at the micrometer and nanometer scales. The SPM technique can characterize the mechanical properties as well as the thickness of individual phases under the non-destructive high-resolution conditions. A new loading mode of the constant vertical loading rate is proposed for continuous fracture properties measurement by nanoscratch technique. The content of this chapter can deepen the understanding of current advanced techniques applied to cementitious materials for testing conducted at micro scale.
