Flexural response of cementitious mortar bars reinforced by 3D printed polymeric mesh

In order to improve the behaviour of cementitious material under in bending, 3D printed polymeric lattice meshes were used as an alternative to fibre reinforcement. Lattice meshes with different cell sizes and different surface roughness were designed and printed. Plain mortar samples and reinforced samples were casted. After curing, 4-point...

Durability of fibre reinforced cementitious composites: Coupling mechanical and chloride environment loads

Fibre reinforced cementitious composites (FRCC) may be characterized by their improved performance namely in terms of tensile ductility, accompanied by multiple cracking, and potentially lower permeability to liquid and gas in cracked state. Cracking, which is nearly inevitable, can occur due to applied structural loading, shrinkage, chemical...

Investigation of the potential use of calcium alginate capsules for self-healing in porous asphalt

Incorporating self-healing technology in asphalt pavement has been demonstrated to have great potential to prolong its service life. To this aim, the calcium alginate capsules encapsulating rejuvenator were manufactured and proved to have sufficient thermal stability and mechanical resistance to survive the asphalt production and compaction...
