An Experimental Study on the Effects of PVA, Jute, and Recron 3S Fibers on Bendable Concrete Properties

In engineering terminology, bendable concrete refers to engineered cementitious composite (ECC), also called strain hardening cement-based composite (SHCC). Crack width control is tight in ECC, which is typically brittle. This composite is easy to mold due to its mortar-based composition. By using natural and artificial fibers such as PVA fiber, steel fiber, and jute fiber, bendable concrete can be made more durable and produce narrow crack widths, as opposed to conventional concrete. The primary aim of this research is to assess the physical characteristics of bendable concrete reinforcement made from M30 mix design with a variety of fiber types, including PVA Jute and Recron 3S fiber. These physical properties include split tensile strength, compression strength, flexural strength test, and ductility. A number of bendable concrete mixtures were created using varying fiber proportions and evaluated for their effectiveness. A fiber-based concrete additive, PVA fibers, have the ability to absorb moisture and expand, which enhances their bond with cement and can enhance concrete's durability and crack resistance. According to the observations, fibers added to concrete improve its ductility and flexural strength. As a result of this study, bendable concrete has the potential to benefit construction in many ways, especially in terms of durability, sustainability, crack resistance, and earthquake resistance. As well as fibers and fly ash can also be used for the production of an environmentally friendly construction material. Moreover, the high-performance construction materials selection process included comparing the cost of different concrete materials.
