In this paper the properties of conventional concrete have been developed. Conventional concrete has the property of high brittleness and less flexural strength. This is a undesirable characteristics is mother of development of Flexible concrete to improve this deficiency. The Polyurethane fiber has the ability to impart considerably flexibility in concrete. For this purpose concrete cube, cylinders and beams experimentally tested. By the mixture of traditional concrete ingredients and special polyurethane fibers addition with water super plasticizers for good workability purpose. The test results have proved to be increased flexibility of the concrete.
Flexural strength, split tensile strength, compressive strength, Polyurethane fiber
