Effects of the Exposure to Fire and Fire Extinguishing Agents on the Behavior of Building Materials

01.Jul.2020

​This study investigates the effect of elevated temperatures on concrete mixes used in Jordan for building purposes; for its mechanical properties; where compression, tensile and impact tests were conducted for the mentioned materials. Additionally, a thermal conductivity test was carried out for thermal properties at ambient temperatures. Standard methods for the examination of concrete were adopted for all conducted measurements. Moreover, a comparison has been drawn between the behavior of normal strength concrete and the behavior of high strength concrete. This research study also examines the effect of the use of water and dry chemical powder extinguishers on the mechanical properties of concrete at elevated temperatures. Results have shown that a loss of concrete compressive, tensile, and impact strengthsare noticed with increasing temperatures and heating duration. The presence of additives in concrete mixtures increases the strength of both high strength concrete and normal strength concrete. Furthermore, the results have shown that the use of water and dry chemical powder as extinguishing agents and did not deteriorate further the compressive strength of the high strength concrete and normal strength concrete.
