Abstract
Engineered cementitious composites are a new kind of fiber-reinforced cementitious composite that exhibits superior performance. They may be used to reduce maintenance and repair costs, extend the service life of buildings, and overcome ordinary concrete's lack of bendability. The purpose of this study was to determine the effect of replacing cement with up to 10% silica fume on the characteristics of Engineered Cementitious Composites concrete with a binder concentration of 1000 kg/m3 and two kinds of fiber (steel and carbon). Numerous experiments were conducted to determine the behavior of Engineered Cementitious Composites concrete, including compressive strength for (cubes and cylinders), tensile strength for splitting, flexural strength, and load-bearing capacity (when slabs at simply supported and fixed). The experimental findings indicated that up to 10% substitution of silica fume for cement increased the compressive strength of this kind of concrete after 28 days. Other parameters such as splitting tensile strength, flexural strength, and load-bearing capacity exhibited the similar pattern.
