Abstract
Concrete with adequately high compressive strength has been in use for structural purposes. However, the majority of these materials continue to be brittle. It has been observed that sometimes the brittleness is increased as the compressive strength rises. This creates potential restrictions on the use of high strength concrete in structures. When there is a contact between concrete and steel, a high stress concentration is produced that may cause a fracture of the concrete. Therefore, use of high ductile concrete becomes necessary for increasing the durability of the concrete structures. This paper focuses on development of Engineered Cementitious Composites (ECC) with increased tensile strain capacity using high tensile strength Polyvinyl Alcohol fiber up to 2 Percent by volume of Concrete. Environmental Scanning Electronic Microscope (ESEM) images show the development of self healing microcracks which depict ECC are a promise to high resilient structures.Keywords- ECC, Fly-Ash, Polyvinyl Alcohol (PVA) Fiber, Superplasticizer.
