Kristopher, Fredo (2018) Pengaruh Variasi Agregat Kasar Daur Ulang (RCA) terhadap Kuat Lentur Balok Beton Self Compacting Concrete (SCC) Bertulangan Baja. Sarjana thesis, Universitas Brawijaya.
Abstract
Self Compating Concrete (SCC) atau beton memadat sendiri adalah sebuah inovasi dalam teknologi pembuatan beton yang tidak memerlukan proses pemadatan untuk menempati bekistingnya. Pada penelitian ini pembuatan SCC digunakan untuk memanfaatkan potensi material agregat kasar daur ulang atau biasa disebut RCA (Recylcled Coarse Aggregate). Variasi yang digunakan adalah variasi balok SCC 100% agregat kasar daur ulang dan balok SCC 0% agregat kasar daur ulang atau bisa disebut balok SCC normal. Balok memiliki tulangan utama 2-Ø12. Pengujian yang dilakukan adalah pengujian filling ability, kuat tekan beton, dan kuat lentur beton. Filling ability SCC diukur menggunakan metode pengujian slump flow test. Pengujian kuat tekan beton dilakukan untuk mendapatkan kuat tekan aktual dari balok. Dari pengujian kuat lentur didapatkan beban ultimit dan lendutan aktual balok. Hasil penelitian yang didapatkan adalah substitusi agregat kasar daur ulang pada balok SCC tidak berpengaruh terhadap kuat lentur balok. Jika dibandingkan dengan balok SCC normal, kuat lentur balok SCC agregat daur ulang yang sebesar 1470 Kgm memiliki prosentase penurunan sebesar 4,8%. Dilihat dari lendutannya, substitusi agrgeat kasar daur ulang pada balok SCC tidak berpengaruh. Jika dibandingan dengan balok SCC normal, lendutan yang terjadi pada balok SCC agregat daur ulang sebesar 7,085 mm memiliki prosontase penurunan sebesar 42,14%. Ini dikarenakan balok SCC normal memiliki fase plastis lebih besar seiring dengan kemampuan balok mengalami deformasi.
English Abstract
Self Compacting Concrete (SCC) is an innovation in technology of concrete manufacturing that does not require compacting to occupy its formwork. In this research the manufacturing of SCC is used in the aggregate group to utilize recycled coarse material or commonly called RCA (Recycled Coarse Aggregate). The variation used is SCC beam of 100% recycled coarse aggregate and SCC beam of 0% recycled coarse aggregate, also known as normal SCC beams. The beams consist of main reinforcement 2-Ø12. The tests conducted are filling ability test, compressive strength test and flexural strength test. Filling ability test SCC is measured using slump flow test. Compressive strength test is conducted to obtain the actual compressive strength of the beam. Flexural strength test is conducted to obtain the ultimate load and the actual deflection of the beam. The result from this research is recycled coarse aggregate substitution of the SCC beam does not affect the beam flexural strength. When compared to the normal SCC beam, the flexural strength of recycled aggregate SCC beam of 1470 Kgm have decreased percentage of 4.8%. Viewed from its deflection, the recycled coarse aggregate substitution of the SCC beam SCC beam has no effect. Compared with the normal SCC, the deflection of recycled coarse aggregate SCC beams of 7.085 mm have decreased percentage of 42.14%. This is because of the normal SCC beam have a larger plastic phase along with the ability of the beam to deform.
