The College of Engineering at the University of Baghdad held the public defense of a Master\u2019s thesis submitted by Hiba Munaim<\/strong>, from the Department of Civil Engineering, entitled \u201cEffect of Fire Flame on Some Properties of Structural Lightweight Self-Compacting Concrete.\u201d<\/strong> The defense was held on Thursday, August 13, 2026, in the Prof. Dr. Khalid Shakir Hall at the College of Engineering, University of Baghdad, under the supervision of Assist. Prof. Rawaa Khalid Aboud<\/strong>.<\/p>\n

The thesis aimed to investigate the effect of direct exposure to fire flame on selected properties of structural lightweight self-compacting concrete. It also examined the possibility of using waste glass<\/strong> as a partial replacement for natural fine aggregate, in addition to evaluating the effect of incorporating 1% micro steel fibers<\/strong> on improving the mechanical properties of concrete and its residual performance after fire exposure. The study also investigated the effects of different cooling methods following exposure to elevated temperatures.<\/p>\n

The thesis included the preparation of structural lightweight self-compacting concrete mixtures using 100% pumice as lightweight coarse aggregate<\/strong>, with natural fine aggregate replaced by recycled waste glass at rates of 0%, 20%, 30%, and 40%<\/strong>. Another group of mixtures was prepared with the addition of 1% micro steel fibers<\/strong>. The fresh and hardened properties of the mixtures were evaluated, after which the specimens were exposed to fire flame at temperatures of 300, 400, and 500\u00b0C for 60 minutes<\/strong>. The study then investigated the effects of two cooling methods following fire exposure: gradual cooling and foam cooling<\/strong>. Mass loss and the residual mechanical properties of the specimens were also evaluated.<\/p>\n

The thesis reached a number of conclusions and recommendations, the most significant of which were:<\/p>\n
