Experimental Investigation and Lattice Modelling of 3D Printed Concrete Buildability quantification and early-age creep behaviour

For some decades now, additive manufacturing has been a revolutionary technology which generates enormous interest in both industrial and academic applications. 3D concrete printing (3DCP), an automated construction method, is able to manufacture the computer-designed model through material deposition. This innovative technique can considerably...

Experimental and numerical study of fatigue behaviour at the microscale of cementitious materials

Ageing is an inherent feature of cementitious materials. Ageing of material leads to gradual loss of the function of a concrete structure with increasing likelihood of failure. As one of the typical ageing phenomena, fatigue of concrete, has recently received considerable research attention. The phenomenon of concrete fatigue is complicated as...

Architected Cementitious Cellular Materials Towards Auxetic Behavior

In recent years, the rapid development of digital fabrication technology has substantially boosted the research of architected cellular materials. Among them, the auxetic materials are a distinct type for their unusual deformation behavior: negative Poisson’s ratio. When loaded longitudinally in compression, in contrast to conventional materials...

Experimentally validated multi-scale fracture modelling scheme of cementitious materials

Cementitious materials are heterogeneous on mutliple length scales, from nanometres to metres. Consequently, their macroscopic mechanical properties are affected by material structures at all length scales. In pursuit of fundamental understanding the relationship between their multiscale heterogeneous material structure and mechanical properties...
