Objectives:

To develop innovative fire suppression system and a methodology for the assessment of fire damage and rehabilitation of fire damaged structural elements as well as prediction of fire behavior of structural elements.

The increasing pressure from all Govt. and world bodies such as UNEPA has augmented the world-wide R&D programmes on development and characterization of water-mist and aerosol fire extinguishants. Halon fire extinguishants (CFC-based) CFCs Phase-out time-limit in India has already been timed out in 2010 for civilian fire protection and other uses under Montreal Protocol. Commercial fixed water-mist and aerosol fire systems are hardly in use in India. Hence, India needs low-cost water-mist fire extinguisher. No variable multiple fire load density based fire suppression system approach for characterizing fire extinguishing materials and designing the fire extinguishing system is reported in the literature. There are relatively very limited studies reported in literature on CFD modeling of fire suppression systems. The optimization of fire suppression systems in many applications is made more challenging and difficult.

Concrete is one of the most commonly used building materials and practically no construction is complete without the use of concrete. Although the concrete is non-combustible in nature but when exposed to high temperature, changes take place in the properties of concrete both at the surface and inside the structural element. Relatively very less research data is available internationally on the fire behavior of structural elements under stressed conditions. Therefore it is required to promote more research programmes on the study of the behavior of structural elements made of concrete at high temperature.
