The concrete members several blessings over steel beam, like high resistance to prominent tem-perature, higher resistance to fatigue and buckling, high resistance to thermal shock, fire re-sistance, robust resistance against, and explosion. However there are some disadvantages as a result of exploitation totally different materials to product it. The most downside of structural concrete member is its deprived the strength to tensile stresses.The bond mechanism between steel bars and concrete is thought to be influenced by multiple parameters, like the strength of the encompassing media, the prevalence of cacophonous cracks within the concrete and therefore the yield stress of the reinforcement. However, properties of concrete mass has significantly effect when it was subjected to elevated temperature.The objective of this paper presents the results that allocating with the bond behavior of the rein-forcement of steel bar systems below static pull-out loading tests subjected to elevated tempera-tures. This numerical technique relies on relative slip and therefore the stress of bond distribu-tions done the embedded length and size of the bar within the concrete cylinder specimens. The obtained results square measure given and commented with the elemental characteristics of ferroconcrete members. The comparison showed smart agreement with experimental results
High performance thermal insulators industries is recognized as one of most significant industries worldwide. This, of course, due to its basic role in industries requiring elevated temperatures. Concerning this target, a former study was performed in production of a thermal insulator containing locally available kaolin taking into consideration the effect of ignition temperature and grain size on the general specifications of the insulator. The low alumina content in kaolin samples , as shown by analysis, has resulted in lowering both the softening and melting points. It is planned in this research to study the effect of soaking time and added alumina on improving physical, thermal and mechanical properties of kaolin sample. Certainly, better properties of sample will result in better performance towards thermal insulation and to be more effective in resisting elevated temperature without affecting other properties.
