چکیده

This study presents the results of an investigation on the use of different levels of cement content to enhancing the strength and near surface properties of concrete mixtures having the same W/C ratio. Three W/C ratios (0.4, 0.45 and 0.5) were used and for each W/C ratio, four mixtures were prepared with cement contents 300, 350, 400 and 450 kg/m3 and tested for compressive strength, water absorption, and sorptivity. Test results indicate that the cement content has significant effects on the strength and near surface durability performance of concrete. At each W/C ratio, decrease in cement content from 450 to 350 kg/m3 greatly increased compressive strength and decreased water absorption and sorptivity in varying magnitudes. Similar results were also observed when cement content increased from 300 to 350 kg/m3. However, decrease in water absorption and sorptivity was little in this case.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
