Abstract AR
في هذا البحث تم دراسة الحرق بلهب النار على بعض الخصائص الميكانيكية للخرسانة ذات المقاومة العالية.
عرضت النماذج الخرسانة إلى درجات حرارة تتراوح بين (20-850) درجة مئوية و بأعمار مختلفة هي (30، 60، 90) يوما حيث تم تعريض النماذج إلى ثلاث درجات حرارية (400، 600، 850) درجة مئوية و لمدة ساعتين.
بع التعرض بردت النماذج بالماء لوحظ من النتائج أن مقاومة الخرسانة للانضغاط و الشد و الإنثناء تتناقص بزيادة الحرارة.
تم استخدام برنامج إحصائي (Data Fit) لتخمين خصائص الخرسانة المعرضة للحرق.
Abstract EN
In this study, some mechanical properties of high strength concrete under the effect of fire flame exposure are presented.
The concrete specimens were subjected to fire flame temperatures ranging from (20-850 °C) at different ages of 30, 60 and 90 days.
Three temperature levels of 400°C, 600°C and 850°C were chosen of exposure duration of 2.0 hours.
After burning, the concrete specimens were quenched in a water tank to provide the maximum shock due to sudden cooling.
The test results showed that the density, compressive strength, tensile and flexural strength decreases when the fire flame temperatures were increased.
Mathematical models were proposed to predict the compressive strength, splitting tensile strength and flexural strength of concrete after exposure to fire flame.
These models made by statistical program called (DATA FIT 9.0.59, 2009).
