الملخص

يهدف هذا البحث لإنتاج خرسانة خفيفة الوزن باستخدام كميات مختلفة من الفلين وكذلك من عامل الرغوة. لذلك فقد تم
استخدام نسب مختلفة من عامل الرغوة كانت بمقدار 4.0 و 4.0 و 4.0 و 0.4 و 0.1 كغم /م 3 مع استخدام نسب متغيرة من
الماء/السمنت بالاعتماد على مقدار الانسياب للخرسانة. تم استخدام نسب مختلفة من الفلين كنسبة حجمية لإنتاج خلطات خرسانية
خفيفة الوزن. مقدار الانسياب التصميمي للخرسانة هو 034 004 %. وتم اختبار الخلطات في مقاومة الانضغاط ومقاومة -
الانحناء والكثافة ونسبة الفراغات. اوضحت النتائج بان استخدام الفلين او عامل الرغوة يمكن من الحصول على خرسانة خفيفة
الوزن مع الحفاظ على مستويات مقاومة الانضغاط والانحناء بمديات مناسبة لاستخدامها كخرسانة انشائية مثل الابنية الهيكلية
المتعددة الطوابق والارضيات والجسور والخرسانة المسبقة الصب او الجهد.
