One of the goals of any building project is to minimize the construction costs. Economically,lot of countries tries to reduce the total costs and it is forcing the construction industry to find new ways to reach that goal. Examples of such materials are self-compacting concrete (SCC) and fiber-reinforced concrete (FRC) and using composite materials. Self-compacting concrete and steel and basalt fibers are combined to create steel and basalt fiber reinforced self-compacting concrete. The present work deals with the workability and strength studies on steel and basalt fiber reinforced self-compacting concrete of grade M30 with GGBS and superplasticizer. The mix proportions for self-compacting concrete were arrived at by performing mix design and then fine-tuning using EFNARC guidelines. The powder content should be added the 70% of cement and 30% of GGBS. This was kept constant for all the mixes. The steel and basalt fiber percentage was varied from 0.6%, 0.8%, 1.0%, 1.2%, 1.4%, 1.6%, 1.8%, and 2.0 % by weight of concrete. And also to taken the data for hardened concrete properties like compressive strength, split tensile strength, flexural strength (single point and double point).
