EXPERIMENTAL STUDY ON UNIAXIAL TENSILE STRENGTH OF BENDABLE CONCRETE

Concrete with adequately soaring compressive strength has been in use for building skyscrapers, pavements, two-dimensional elements like plates and slab-decks, threedimensional solid masses like retaining walls and dams. However, majority of these structural elements continue to be brittle in nature. Generally, the compressive strength is directly proportional to brittleness. This creates prospective restrictions on the use of high strength concrete. A high stress concentration at junctions of concrete and steel is not uncommon 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 Crack-free and High Ductile bendable concrete which has a tensile strain capacity of 1.67 percent for a Polyvinyl Alcohol fiber content of 2.0 percent by volume of concrete and the specimens revealed microcracks less than 153µm when subjected to Uniaxial test. Various transport properties like Rapid Chloride Penetration, Sorptivity, and Permeability of Bendable Concrete at the age of 28 days are also studied.
