Prof. S. Suriya Prakash of the Department of Civil Engineering’s Castcon Laboratory and his research group have developed an affordable special ultra-high performance fiber reinforced concrete (UHPFRC), the Indian Institute of Technology-Hyderabad has said.
The concrete was developed using locally available materials like cement, fly ash, river sand, ground granulated blast furnace slag, micro-silica, water, steel fiber, fiber polypropylene and high range water reducing agent (HRWRA), he said.
IIT-H said the concrete was half the price of commercially available proprietary products. Its cost has been reduced by reducing the amount of cement, fibers and replacing expensive fine aggregates with cheaper aggregates available locally, according to the statement.
IIT-H said the composition combines the best characteristics of self-consolidating concrete (SCC), fiber-reinforced concrete (FRC) and high-performance concrete (HPC).
Congratulating Professor Suriya and his team, Professor BS Murty, Director of the IITH, said: “Developing building materials with improved strength using locally available raw materials is a commendable step towards realizing our dream of ‘Atma Nirbhar Bharat.
Prof. Prakash, CASTCON Lab and Chandrashekhar Lakavath, Researcher, said: “The aim was to develop affordable high performance concrete using locally available materials and to carry out extensive material categorization to understand the behavior of UHPC in compression, tension, rupture and direct shear. Several full-size UHPFRC bridge girders were tested.
