الخرسانة ذات القوة العادية، الخرسانة المقاومة للكبريتات، خرسانة مسحوقية تفاعلية باستخدام الأسمنت البورتلاندي النوع V، ألياف الصلب، Steel Meshesالملخص
في مدينة الكرخ ببغداد، يعد ضمان القوة الهيكلية للعوارض الخرسانية المسلحة تحت الأرض أمرًا ضروريًا. تتعمق هذه الدراسة في المزايا المحتملة لدمج الألياف الفولاذية (SF) والشبكات الفولاذية (SM) في هذه العوارض باستخدام ثلاثة أنواع من الخرسانة، الخرسانة الاعتيادية (NSC)، والخرسانة المقاومة للكبريتات (SRC)، والخرسانة المسحوقة التفاعلية (RPC). بدلاً من استخدام الأسمنت البورتلاندي العادي، تستخدم الخرسانة المسحوقة التفاعلية (RPC) المستخدمة في هذه الدراسة الأسمنت البورتلاندي من النوع الخامس، المعروف بمقاومته للكبريتات. تحليل قدرتها على حمل الحمولة وخصائص الانحراف. تشير النتائج الأولية إلى أن الحزم المعززة بـ SF وSM تعرض كفاءة معززة في تحمل الأحمال، وتقليل الانحراف، وتحسين المرونة ضد الضغوطات البيئية. سيؤدي دمج كل من SF وSM إلى زيادة الحمل النهائي لـ NSC وSRC وRPC بنسبة 55% و69% و119% على التوالي. ومن الجدير بالذكر أن وجود الشبكات الفولاذية كان مرتبطًا بزيادة قوة الشعاع. يؤكد هذا البحث على الفوائد الهيكلية المحتملة لـ SF وSM. ومن الممكن أيضًا استخدام الأسمنت البورتلاندي من النوع V في RPC، مما يؤكد إمكانية التطبيق في الأطر الحضرية تحت الأرض، خاصة في السياقات التي تعكس ظروف الكرخ.
