Description
Summary:Fire presents a significant danger to the survival of the building and inhabitants, adverse effects at the structural level. In view of this, several researchers have measured the fire efficiency and behavioural characteristics of concrete under varying temperatures. Using indirect measures such, water permeability, as chloride ion permeability absorption and sorptivity, the resilience of concrete after fire exposure is assessed. In most previous literature, residual mechanical properties mentioned may be overvalued, where cooling was typically employed. Proper assessment of concrete fire resistance requires more experimental data found under different cooling environments, such as water spraying or water quenching. Design considerations and analytical methods are provided to determine the reaction of reinforced concrete structures to elevated-temperature settings. Related studies in which reinforced concrete structural components have being exposed to cyclic loading. The purpose of this review is to provide a description of the elevated temperature characteristics of the performance of concrete ingredients and structures. The impacts of high temperatures on high-strength concrete materials are observed and their quality is compared to standard concrete strength.
