الملخص

المواد البيئية هي تلك التي تستخدم في المشاريع لتقلل من التأثير البيئي للمشروع، وتساعد على تحسين نوعية الحياة للأشخاص الذين يعيشون ويعملون في المنشأة، وتقلل من التلوث البيئي. يحظى النفط بأهمية كبيرة على المستوى الاقتصادي، فهو أحد الموارد الأساسية في العجلة الاقتصادية بين دول العالم. إلا أن استخدام هذا المورد يواجه العديد من التحديات، فهو من الموارد الناضبة والمهددة بالفناء، ناهيك عن المشاكل البيئية الناتجة عن صناعة النفط في مراحلها المختلفة. يهدف هذا البحث إلى تشخيص مشكلة الأسمنت العراقي حيث تكمن مشكلة الأسمنت العراقي في أن محتواه من السيليكا منخفض حوالي 18%، وقوته منخفضة، وزمن سماكته قصير، بالإضافة إلى نعومته العالية، وتصلبه السريع. الجديد في هذا البحث هو استخدام أوراق السدر وقشور الجوز المطحون وغبار السيليكا كمضافات صديقة للبيئة وبيان تأثيرها على خواص الأسمنت العراقي. أجريت الاختبارات على المواد المذكورة بحجمها الطبيعي وبجزئيات متناهية الصغر، إذ أظهرت النتائج أن كل من قشور الجوز المطحون وغبار السيليكا ساهمت في زيادة قوة الضغط للأسمنت العراقي، كما أن المواد بحجمها النانوي 100 نانومتر كانت أفضل مما هي عليه في الحجم الطبيعي. أظهرت النتائج أن ورق السدر بحجم النانو قلل من كثافة الملاط لاحتوائه على مادة الصابونين عند إضافة 1.5% BWOC. ومن أهم استنتاجات البحث أن إضافة غبار النانو سيليكا بنسبة 1.5% BWOC أدى إلى زيادة قوة مقاومة الأسمنت بحوالي 3 أضعاف ما كانت عليه بدون إضافة عند درجة حرارة 38 درجة مئوية.
