As the most popular construction material, concrete has many advantages compared to other materials. However, its brittle nature causes cracking and results in many deterioration problems and failures in infrastructures. Considering the issue of sustainability, researchers around the world have conducted numerous studies to develop concrete that has better performances, higher durability, longer life span, and less damaging effects to nature. To obtain such characteristics, researchers not only focus on strength enhancement, but also ductility and toughness.
This thesis examines the effect of using ground granulated blast furnace slag as partial cement replacement in producing engineered cementitious composite (ECC), a ductile cementitious composite reinforced with short random PVA-fiber. Slag replacement is not only to increase the strength but also to create better fiber bridging property that results in better ductility of the material. Variables involved in the mixture proportions are the amount of slag replacement, slag fineness, and water content. The mechanical behaviors of ECC under uniaxial tensile tests and flexural tests as parameters to measure its ductility will be reported.
