SYNOPSIS AND BIODATA OF SPEAKER

Part 1: Technical Talk on “UNDERSTANDING FIRE DAMAGE TO TUNNEL LINING STRUCTURE”

This talk will focus on understanding the effects of fire damage on tunnel lining structures, particularly how high temperatures impact concrete and steel reinforcement. It will explore key issues such as concrete spalling, loss of strength, and the degradation of materials during fire exposure. The talk will also cover methods used to assess fire resistance in tunnel linings, including thermal testing and simulations, to better understand how temperature distribution and moisture content affect the structure’s integrity. This session is designed to provide valuable insights for engineers and professionals working to enhance the fire safety and durability of tunnel infrastructure.

Part 2: Technical Talk on “FIRE RESISTANCE MATERIALS FOR TUNNEL LINING STRUCTURES”

The increasing frequency of fires in buildings, factories, tunnels, and chemical and gas facilities highlights the growing need to understand the fire resistance of concrete structures exposed to high temperatures. This talk focuses on the development of new fire-resistant materials, specifically High-Strength Fly Ash and Nano Silica Concrete, designed to withstand temperatures exceeding 1000°C. The session will cover advanced technologies used to assess the performance of these materials, including furnace heating, thermal conductivity testing, and finite element simulations. These new materials offer promising solutions for enhancing the fire resistance and safety of tunnel lining structures, making them more resilient to extreme fire conditions.
