Mitigation For Fire-Induced Spalling in Concrete by Reused Tyre Polymer Fibres

Abstract

With the increased incidents of major fires in buildings; assessment, repairs and rehabilitation of fire damaged structures has become a topical interest. This is a specialized field involves expertise in many areas like concrete technology, material science and testing, structural engineering, repair materials and techniques etc. Research and developmental efforts are being carried out in this area and other related disciplines. In this topic the experience of real life problems are presented which add immense value to this. This topic also gives a Comprehensive knowledge on the overall strategy for the restoration of fire damaged buildings and also presents a critical appraisal of the assessment procedures by different non destructive techniques, specifications and execution of repair techniques. The experimentation has been done to find out the impact of the fire on concrete and reinforcement steel bars by heating. The heated samples are rapidly cooled by quenching in water and normally by air cooling. The change in the mechanical properties are studied using universal testing machine (UTM), CTM, two point flexural test and the microscopic study of grain size and grain structure is studied by scanning electron microscope (SEM). This study is conducted to accomplish some predefined objectives. These objectives are to:
