Abstract AR
خلال السنوات القليلة السابقة زاد الاهتمام باستخدام الخرسانة العالية المقاومة في مجال هندسه التشييد والبناء.
وعلى الجانب الأخر ظهر استخدام الألياف المعدنية في مجالات متعددة لما لها من مميزات عديدة.
هذا البحث يناقش تأثير استخدام الألياف المعدنية بنسب مختلفة على مقاومه الضغط ومقاومة الشد للخرسانة عالية المقاومة والمصنعة بإضافة السليكا مع أو بدون النانو سليكا.
تم صب 16 خلطة وتقسيمها إلى 3 مجموعات حسب متغيرات الدراسة السابقة وتم عصر النتائج ووجد أن الحلقات التي تحتوي على ألياف معدنيه عند عمر 28,7 و56 يوم كانت مقاومه الضغط لها 1.0 ,1.04 ,1.12 ومقاومه الشد عند عمر 28 يوم كانت 7.22%.
Abstract EN
During the past few years, high-strength concrete (HSC) has been increased interest amongst civil and structural engineers.
on the other hand, several varieties of fiber-reinforced concretes are now utilized in the building sector for a variety of purposes.
this paper discusses the influence of using steel fiber on the compressive strength and splitting strength of high strength concrete with Nano-silica (NS) and / or silica fume (SF).
the experimental effort consists of casting and testing 16 distinct mixes.
all of the mixes have the same cement content, and some have the same water content and aggregate content, but they differ in factors such as the quantity of NS, SF, and steel fiber.
the mixes have been categorized into three main groups.
in group one, the impact of adding 3% sf and / or 2% ns was investigated.
in group two, the effect of adding 10% sf and the sources of type f admixtures was studied.
in group three, two subgroups to study the effect of adding 5% sf, as well as the effect of w / c ratio were considered.
as a results, it is established that the average compressive strength of mixes containing fibers to the compressive strength of samples without fibers at 7, 28 and 56 days is 1.04, 1.0 and 1.12, respectively.
the average ratio of splitting strength to compressive strength at 28 days is around 7.22%.
