Abstract –

Engineered cementitious composites (ECC), often known as bendable concrete, are mortar-based composites that can be easily moulded and are reinforced with carefully chosen short random fibres. When stretched by an earthquake or by frequent abuse, traditional concrete fails catastrophically. At tensile loads of up to 5%, ECC is undamaged and safe to use. At 0.01% tensile strain, conventional concrete fractures and may not be able to support a load. In this study, poly vinyl alcohol fibre is utilised to minimise cement content and increase flexibility in order to meet future demand for concrete while also developing fibre materials.  PVA fiber has an excellent affinity for water, a high aspect ratio, a high ultimate tensile strength, a moderately high modulus of elasticity, strong chemical compatibility with Portland cement, and no health risks. Super plasticizer is used to make concrete easier to work with. During the flexural strength test, the concrete's bendability properties are examined together with the cubes and slabs compressive and flexural strengths.
