Concrete is relatively strong in compression and weak in tension. Also cracks start to form as soon is concrete is placed and before it has properly hardened. Cracks are major cause of weakness in concrete leading to subsequent fracture, failure and lack of durability. Weakness in tension can be overcome by use of conventional rod reinforcement. Composite reinforcement is an interesting and attractive alternative to conventional steel bars reinforcement since it significantly increases the structure durability due to its high corrosion resistance. Basalt fibre is the material of choice presently and is an inorganic fiber with extremely high strength, improved strain to failure, high temperature resistance, excellent stability, good chemical resistance, and natural, eco-friendly and inexpensive. This project studies corrosion resistance behavior of basalt rebars in comparison with steel bars. Study reveals that basalt bar perform better corrosion resistance than steel bars. Self-sensing concrete has the capability to sense the conditions itself such as crack, damage, strain, deformation etc. through incorporating functional fillers or sensing component. It is also known as self-monitoring or self-diagnosing concrete. Here conductive fillers are going to be incorporated as additives to concrete. The conductive fillers using in this study are nanomaterials such as multi-walled carbon nanotube, carbon black, carbon fibre powder and graphene. The preliminary test of cement and aggregates were done. Mix is fixed based on the workability tests and compressive strength tests as per IS 10262:2009. Electrical resistivity of trial concrete cube specimens with and without carbon black were measured. The cube specimens with carbon black showed good change in electrical resistivity response than specimens without carbon black, under the application of load. Electrical resistivity, change in electrical resistivity due to the application of load and mechanical properties of specimens incorporated with different conductive fillers are to be evaluated.
