Abstract

Sample preparation is the first step and the prerequisite for successfully conducting the micro scale tests. This chapter summarizes the key points during the preparing process of cementitious materials samples in terms of the procedures of mixing, casting, curing, hydration stoppage, epoxy impregnation, grinding, polishing, and storage. The major conclusions include but not limited to which the epoxy impregnation is encouraged to be used in preparing the samples for NI test, but not for MI test and for characterizing the ITZagg-paste properties by using SPM test, especially for high w/cm ratio cementitious materials. The fine grinding process should adopt less vertical force, lower grinding rate, and shorter grinding time as possible until a slight reflection phenomenon is observed, etc. The content of this chapter can serve as a detailed guidance for preparing qualified cementitious materials samples for the microstructure and the mechanical tests conducted at micro scale.
