Abstract

Nowadays fire accidents are happening in most of the buildings which causes heavy damage to the buildings and result in loss of durability. In order to avoid the consequences an experimental investigation is carried out using mesh confinement concrete. Concrete is a non combustible material and has a slow rate of heat transfer. High temperature can cause the formation of cracks. These cracks resembles like any other cracks propagation may eventually cause loss of structural collapse and shorting of span life. One mighty problem which occurs when concrete is exposed to fire is spalling. This is the phenomenon in which explosion ejection of chunks in concrete from the surface of the material, due to the breakdown in surface tensile strength. In order to reduce early cover spalling, a new idea has been investigated. This is implemented by installing relatively cheap materials such as glass mesh, nylon mesh, GI weld mesh and wire mesh in cylindrical specimens with a length of 300mm and 150mm diameter. It has been understood from the literature to reduce the spalling in concrete and strength can be improved by mesh confinement. Hence an experimental investigation will be done to study the performance of mesh confinement concrete subjected to fire. M.
