Explanation:

• According to the sources, The Uttar Pradesh public works department (PWD) will have a tie-up with IIT-Kanpur to develop ultra high-performance concrete (UHPC) after research and development.

Key Points:-

=> Currently, M60 cement grade is used in most civil works in the state.

=> UHPC, which has a longer shelf life and can be 4-6 times stronger than M60 grade, and can significantly reduce the department's carbon footprint.

=> This reduction would be achieved by using thinner sections and lower deck heights during the construction of bridges, flyovers, elevated roads, railway overbridges, and other concrete-intensive infrastructure projects.

=> The product, developed using nanotechnology, is expected to be ready in three years.
