Ishaq, Muh. Nurul (2019) Pengaruh Variasi Pilin Serat Kaleng terhadap Kuat Lentur, Lendutan, dan Pola Retak Balok Beton Bertulang. Sarjana thesis, Universitas Brawijaya.
Abstract
Bangunan gedung merupakan hasil pekerjaan kontruksi secara fisik yang menyatukan berbagai komponen struktur sebagai kesatuan untuk mendistribusikan beban dari atas sampai ke bawah. Kekuatan komponen struktur sangat bergantung pada bahan dan dimensi yang akan digunakan. Secara umum, bahan yang paling sering digunakan yaitu beton bertulang. Pada zaman sekarang, inovasi mengenai beton bertulang sudah semakin banyak, terutama penelitian mengenai beton serat. Serat yang digunakan berupa serat kaleng. Penggunaan serat kaleng ini merupakan langkah yang tepat dalam upaya mengurangi sampah, mengingat banyaknya bencana banjir yang disebabkan meluapnya air sungai akibat penumpukan sampah di sungai. Hal ini membuat peneliti ingin meneliti pengaruh variasi pilin serat kaleng terhadap kuat lentur, lendutan, dan pola retak balok beton bertulang. Penelitian ini memanfaatkan limbah serat kaleng yang telah dipotong dengan ukuran 4 cm dan lebar 2 mm serta dipilin sebanyak 1x dan 1,5x. Fraksi serat kaleng yang digunakan adalah sebesar 10% dari volume balok (15x20x130) cm. Pengujian dilakukan pada balok beton bertulang setelah berumur 28 hari. Perencanaan dan pengujian balok menggunakan beban terpusat di tengah bentang. Pengukuran lendutan menggunakan LVDT yang diletakkan di kedua sisi di tengah bentang balok. Sedangkan pola retak diamati secara visual dan penggunaan Dyno lite untuk mengukur lebar retak balok. Hasil pengujian kuat lentur balok menunjukkan bahwa penambahan serat kaleng pada balok beton bertulang kurang berpengaruh. Hasil pengamatan lendutan dan lebar retak balok menunjukkan bahwa penambahan serat kaleng yang telah dipilin sebanyak 1,5x dapat mengurangi nilai lendutan dan lebar retak. Nilai lendutan dan lebar retak balok serat kaleng yang telah dipilin 1,5x masing-masing berkurang sebesar 10-15 % dari nilai lendutan balok normal dan berkurang 23,85% dari nilai lebar retak balok normal. Hasil pengamatan pola retak menunjukkan bahwa balok normal dan balok dengan penambahan serat kaleng memiliki pola retak geser lentur.
English Abstract
Building is the result of physical construction work that brings together various structural components as a unit to distribute the load from top to bottom. The strength of structural components depends on the material and dimensions to be used. In general, the most commonly used material is reinforced concrete. Nowadays, there are more innovations regarding reinforced concrete, especially research on fiber concrete. Fiber used is can fiber which is household waste. The use of can fiber is the right step to reduce waste, given the large number of floods caused by overflow of river water due to the accumulation of garbage in the river. This makes the researcher want to examine the effect of variety in fiber can towards flexural strength, deflection, and crack pattern of reinforced concrete beams. This study utilizes can fiber waste which has been cut to 4 cm in size and 2 mm in width and twisted as much as 1x and 1.5x. Volume fraction of can fiber is 10% of the volume of the beam (15x20x130) cm. Testing done on reinforced concrete beams age 28 days. Planning and testing beams using a centered load in the middle of the beam. Deflection measurement uses LVDT placed on both sides in the middle of the beam. While the crack pattern is observed visually and Dyno lite is used to measure the crack width of the beam. The results of beam flexural strength testing indicate that the addition of can fibers to reinforced concrete beams does not significantly influence. The results of observations of deflection and crack width of the beam indicate that the addition of 1,5x twisted can fibers can reduce the deflection and the crack width value significantly. The deflection value and the width of the cracked can fiber beam which has been twisted 1,5x are reduced by 10-15% from the normal beam deflection value and reduced by 23,85% from the value of the normal beam crack width. The results of observations of crack patterns indicate that normal beams and beams with can fibers have a flexible-shear crack pattern.
