چکیده
بتن معمولی معمولاً مقاومت کششی و شکل پذیری کمی را نشان می‌دهد. از این‌رو، افزودن الیاف به بتن معمولی موجب افزایش مقاومت کششی و خمشی، به همراه بهبود شکل پذیری می‌گردد. علاوه بر این، افزودن الیاف نه‌تنها باعث افزایش مقاومت مکانیکی بتن نسبت به انواع معمولی آن می‌شود، بلکه موجب کاهش عرض ترک‌ها نیز می‌گردد. این امر در نهایت به بهبود دوام و افزایش عمر مفید سازه‌های بتنی، به‌ویژه در محیط‌های دریایی و خورنده، کمک می‌کند. مقاومت کششی بتن تقویت‌شده با الیاف، به طور مستقیم با تعداد الیاف عبوری از عرض ترک و رفتار الیاف در هنگام بیرون کشیده شدن از ماتریس بتنی مرتبط است. بنابراین، درک دقیق رفتار بیرون آمدن الیاف از ماتریس بتنی، برای فهم رفتارهای کششی تک‌محوره و خمشی بتن تقویت‌شده با الیاف اهمیت زیادی دارد. الیاف بازالتی تابیده به دلیل مزایای ذاتی خود از جمله مقاومت در برابر خوردگی، سازگاری با محیط‌زیست‌، استحکام کششی بالا و مدول الاستیسیته مناسب نسبت به الیاف فولادی، در بتن مسلح استفاده می‌شوند. از این رو، بررسی و درک رفتار دقیق بیرون کشیدن الیاف بازالتی تابیده از اهمیت بالایی برخوردار است. در این پژوهش به بررسی تحلیل رفتار بیرون کشیدن الیاف بازالتی تابیده در جهت‌های مختلف نسبت به امتداد محور طولی نمونه‌ها پرداخته شده است. این تحقیق تأثیرات زاویه‌های تمایل الیاف (0، 30، 45 و 60 درجه) و طول‌های مختلف الیاف مدفون (8، 15 و 22 میلی‌متر) را بر پارامترهای پاسخ بیرون کشیدن، مانند بیشینه نیروی بیرون کشیدگی، لغزش در بیشینه نیرو و انرژی بیرون کشیدگی بررسی و تحلیل می‌کند.

چکیده English

Normal concrete typically demonstrates minimal tensile strength and ductility. However, the addition of fibers to NC results in enhanced tensile and flexural strength, along with improved ductility. Moreover, the inclusion of fibers not only increases mechanical resistance compared to conventional concrete but also mitigates crack width, thus augmenting the durability and service life of concrete structures, particularly in marine and corrosive environments. The tensile strength exhibited in Fiber-Reinforced Concrete correlates directly with the quantity of fibers traversing the crack width and the behavior of individual fibers during pull-out. Therefore, a thorough understanding of fiber pull-out behavior from the concrete matrix is crucial for comprehending the uniaxial tensile and flexural behaviors of FRC. Twisted basalt fibers are used in reinforced concrete due to their inherent advantages, including corrosion resistance, environmental compatibility, high tensile strength, and suitable Young’s modulus compared to steel fibers. Consequently, investigating and comprehending the precise pull-out behavior of twisted basalt fibers holds paramount significance. This study investigates the pull-out behavior of twisted basalt fibers at various orientations relative to the longitudinal axis of the specimens. The study investigates and analyzes the effects of fiber inclination angles (0, 30, 45, and 60 degrees) and embedded fiber lengths (8, 15, and 22 mm) on pull-out response parameters such as peak pull-out force, slip at peak load, and pull-out energy.
