(اجابة السؤال الاول)

المتانة( تحمل الخرسانة مع الزمن ) Durabilty
هى تحمل الخرسانة للظروف التي صممت من اجلها مع مرور الزمن دون حدوث تلف او تفتت بها.
او بمعني اخر هى مقاومة الخرسانة للتدهور سواء الناتج من عوامل داخلية (التفاعلات الكيميائية – التغيرات الحجمية - … الخ))
عوامل خارجية (ظروف التشغيل – التحميل – العوامل الجوية .
