Study on Behaviour of Hybrid Fibre Reinforced Cementitious Composites

This paper highlights the material properties of the Bendable concrete for the effective development of new structures and maintenance of existing structures. The material researchers have conducted a lot of experiments based on sustainability, durability and safety point of view. As a result of the attempts, finally a new material was established in the last decade. The proper selection of the fibre, mixing of the composite exhibit strain hardening and multiple cracking behaviour of the material. The strain hardening behaviour of the Bendable concrete gives significant advantage under flexural loading. The crack width developed under loading is very small when compared with conventional concrete due to the bridging effect of the fibre. The material properties of Bendable concrete reinforced with following 0.5 , 1.0 , 1.5 , 2 of steel fibre and 0.1 , 0.15 , 0.2 , 0.25 of polypropylene fibre. The optimum strength attained at 1.0 of steel fibre and 0.1 of polypropylene fibre and has been claimed to be the most promising proportion of the fibre content. A series of experiments were carried out to determine the compressive strength, tensile strength and flexural characteristics of Bendable concrete.
