Adobe is one of the most ancient forms of masonry. Adobe bricks are sundried mixtures of clay, silt, sand and natural fibres locally available joined together using mud mortar. Adobe structures are largely spread in areas of the world prone to earthquakes or involved in military conflicts. Unfortunately, almost no literature concerns the dynamic...

Soft inclusions, such as capsules and other particulate admixtures are increasingly being used in cementitious materials for functional purposes (i.e. self-healing and self-sensing of concrete). Yet, their influence on the fracture behaviour of the material is sometimes overlooked and requires in-depth study for the optimization of mechanical...

The aim of this work is to investigate the fracture process of concrete under various boundary conditions. Although numerous concrete fracture tests have been reported, showing the failure behavior of concrete, their evaluation is ambiguous due to the limitations of specimen size and experimental conditions. Therefore, it is necessary to use...

Nanoindentation is usually used to investigate local elastic properties and hardness of materials. In this paper, the nanoindenter served as a loading tool to perform micro scale bending tests and measure the global response of micro-scale specimens. For testing, cement paste cantilever beams with a square cross-section of 300 μm × 300 μm were...

The potential of using phase change materials (PCM) in cementitious materials to mitigate damage due to thermal loadings has been recently focus of intensive research. In the case of PCM with transition temperatures near to the freezing point of water, their potential to delay frost in a cementitious matrix has been largely investigated through...

Strain hardening cementitious composites are a class of cementitious materials showing metal-like (i.e. pseudo-plastic) behavior in tension due to their multiple cracking ability. This is commonly achieved through use of fiber reinforcement (such as PVA) or, similarly, textile reinforcement (TRC). Increasing the ductility is important in...

Traditionally, mechanical properties of cementitious materials are designed<br/>“chemically”, namely by configuring their mix proportions. Owning to the development of 3D printing technology, “physical” tailoring the meso-structure of cementitious materials to design their mechanical properties becomes possible. In the present study,...

This work aims to investigate the mechanical properties of the cement paste-aggregate interface by combining experimental and numerical approaches. The multi-phase interface microstructure was obtained by X-ray computed tomography (XCT) and submitted to a discrete fracture lattice model for fracture analysis. Apart from the modelling, a...
