Due to the fast rise in material and transportation costs, the recycling of construction<br/>waste has become a critical operation in the construction industry. With the rise in<br/>construction and demolition operations in the construction sector, the relevance of this<br/>process has grown even more. Furthermore, the environmental risks associated with<br/>rising carbon emissions have made the recycling of construction debris an unavoidable<br/>operation. Building debris that has been recycled can be utilized as aggregate in the<br/>construction of a new reinforced concrete structure. Therefore, the use of construction<br/>waste as coarse aggregate should be researched to ensure that the structural behavior of<br/>these structures does not differ from that of non-recycled (natural) coarse aggregate<br/>buildings (NCA).<br/>An experimental investigation was undertaken in this study to explore the influence<br/>of recycled coarse aggregate (RCA) on reinforced concrete beams with pure torsion<br/>apertures. To research crack pattern, failure mechanism, failure load, torque-rotational<br/>angle relation, load-strain relation for longitudinal reinforcement, opening and edge<br/>stirrups, and toughness, various RCA ratios are utilized in the construction of RC beams.<br/>Six beams with identical cross-sectional dimensions of 150 x 350 mm and a total span of<br/>1400 mm are included in the investigation. The overall beam length was split into three<br/>sections, with the center section serving as the test zone and measuring 1000 mm in<br/>length. The two cantilevers were 200 mm wide and 350 mm long, and the tested beams<br/>included two solid beams and four beams having 300 x 150 mm openings. The RCA<br/>replacement ratios of the tested beams were separated into four groups: 0 percent, 30%,<br/>50%, and 100%. At the ages of 7 and 28 days, six cubes are built from each group to<br/>investigate compressive strength.<br/>The results of the experiments revealed that the existence of an aperture in a beam<br/>reduces cracking and ultimate torque. The results of concrete mixes with 30 percent and<br/>50 percent RCA replacement ratios are nearly identical to those of conventional concrete.<br/>When compared to concrete mixes with 30 percent, 50 percent, or standard RCA<br/>replacement ratios, the concrete mix with a 100 percent RCA replacement ratio yields<br/>worse outcomes. The crack patterns for the specimens manufactured with NCA and RCA<br/>are identical, according to the tests done on RC beams. However, beams created with<br/>30% and 50% RCA replacement ratios have about the same capacity and durability as<br/>NCA-made beams. For beams with a 100 percent RCA replacement ratio, the results are<br/>lower |

يتناول هذا البحث دراسة عملية حول تأثير استخدام ركام كبير مُعاد تدويره في الكمرات الخرسانية ذات الفتحات و المعرضة لعزوم لي ،حيث تم اختبار ست كمرات خرسانية مسلحة ، اثنتان منهما بركام طبيعي إحداهما بدون فتحة و الاخري بفتحة .و الكمرة الثالثة فتم استخدام ركام كبير مُعاد تدويره بنسبة 30% مع وجود فتحة في منتصف الكمرة . و للكمرتين الرابعة و الخامسة فتم استخدام ركام كبير مُعاد تدويره بنسبة 50% و احدي الكمرتين بدون فتحة و الاخري بفتحة. الكمرة السادسة فتم استخدام ركام كبير مُعاد تدويره بنسبة100 % بوجود فتحة أيضا.هدف هذا البحث هودراسة شكل الانهيار وحمل الكسر و العلاقة بين الحمل و الانفعال للحديد و كذلك عزم اللي و زاوية الدوران للكمر المُعاد تدويره.<br/><br/> |
