Abstract: The porous volume of cement-based concrete is the key to understand its mechanical properties and durability. In this research, we apply X-ray tomography (XRT) and focused ion beam/scanning electron microscopy (FIB/SEM) ...

Abstract: The point-load test method (PLTM) commonly used in the geotechnical area is shown in this paper to estimate the compressive strength of in situ masonry mortar. A specially developed portable PLTM instrument was used for ...
