Cementitious composite is one of the most widely used construction materials in the world because its abundant resources, strong adaptability and mature production process [1]. Despite cementitious matrices present good compression strength, they are brittle and usually break when suffer some strain caused by tensile effort. Aiming to overpass this problem some fibers can be used as reinforceme...
With the advent of strain-hardening cementitious composites (SHCC), an opportunity for alternative jacketing solutions is presented, where internal confinement exerted by fibers in material may effectively encase structural component, thereby enhancing strength and deformation capacity critical regions. This concept explored present paper through testing four pre-damaged prismatic flexural rein...
Engineered cementitious composites (ECC) is distinct for the tensile strain-hardening behaviourand ductility contrasting to quasi-brittle nature of ordinary concrete. The blended materials ECC only consist cement, sand, water, fibre, and admixture. depleting limited resources sand in many countries have led research on alternative replace partially or fully concrete mixture. Therefore, this stu...
The current paper presents a bacteria-based self-healing cementitious composite for application in low-temperature marine environments. The composite was tested for its crack-healing capacity through crack water permeability measurements, and strength development through compression testing. The composite displayed an excellent crack-healing capacity, reducing the permeability of cracks 0.4 mm ...
Concrete fracture failure is often observed at interaction zones between steel and concrete, including those in hybrid structure connections, shear studs in composite beams, and steel fasteners in concrete. Improvement in intrinsic ductility of the concrete material should suppress such failure mode and enhance the overall structural performance. In this paper, we introduce and experimentally d...
