Abstract

Salah satu unsur terpenting dalam suatu bangunan adalah beton. Beton dengan workability tinggi merupakan suatu inovasi pembuatan beton dalam usaha untuk menciptakan beton yang memiliki kinerja yang lebih baik dari beton konvensional. Aluminium merupakan limbah hasil pabrik pekerjaan aluminium yang tidak terpakai bila tidak diolah dapat mencemari lingkungan. Penggantian sebagian pasir menggunakan serbuk aluminium merupakan salah satu usaha menjadikan beton lebih ramah lingkungan. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan serbuk aluminium sebagai pengganti sebagian pasir ditinjau dari kuat tekan beton. Penelitian ini menggunakan metode eksperimen dengan total 16 bendanuji. Benda uji berbentuk kubus 15x15x15 cm dan menggunakan variasi komposisi serbuk aluminium 5%, 10% dan 15%. Setiap jenis campuran beton dibuat 4 benda uji. Mutu beton yang direncanakan adalah fc’ = 29,05 MPa. Uji kuat tekan dilakukan pada umur 28 hari. Kekuatan tekan beton standar kurang dari 100.% saat umur 28 hari ( 326.kg./cm2 < 350.kg./cm2 ). Perlemahan kekuatan tekan beton dengan variasi material pengganti 5% umur 28 hari ( 111,359kg/cm2. < 350.kg./cm2 ). Perlemahan kekuatan tekan terjadi pada beton dengan variasi material pengganti 10% umur 28 hari ( 71,612kg/cm2 < 350.kg./cm2 ), dan perlemahan kekuatan tekan beton dengan variasi 15% adalah sebesar ( 9,69kg/cm2 < 350.kg./cm2 ). Dari hasil uji kuat tekan dapat disimpulkan bahwa pengunaan bahan pengganti serbuk aluminium tidak bisa meningkatkan kuat tekan beton dan malah membuat beton menjadi rapuh.Nilai slump beton terjadi penurunan seiring dengan bertambahnya kadar pemakaian bahan pengganti. Nilai slump paling besar yang diperoleh ialah 11 cm pada beton normal dengan kadar 0%. Dari hasil uji kuat tekan dapat disimpulkan bahwa pemakaian material pengganti tidak bisa menambah tingkat kemudahan pekerjaan atau workabilitas beton. Kata Kunci : Analisa, Kuat Tekan, Beton, Serbuk Aluminium ********************************************************************** One of the most important elements in a building is concrete. High workability concrete is an innovation in making concrete in an effort to create concrete that has better performance than conventional concrete. Aluminum is a waste product from aluminum work that is not used if not processed can pollute the environment. Replacement of some sand using aluminum powder is one of the efforts to make concrete more environmentally friendly. This study aims to determine the effect of using aluminum powder as a substitute for some sand in terms of the compressive strength of concrete. This study uses an experimental method with a total of 16 tests. Test specimens in the form of cubes 15x15x15 cm and using variations of aluminum powder composition 5%, 10% and 15%. Each type of concrete mixture is made of 4 specimens. The planned concrete quality is fc '= 29.05 MPa. The compressive strength test was carried out at 28 days. Normal concrete compressive strength is less than 100% at 28 days (326kg/cm2 <350kg / cm2). Decreasing the compressive strength of concrete with a variety of replacement materials 5% 28 days old (111,359kg/cm2 <350kg/cm2). The decrease in compressive strength occurs in concrete with a variation of replacement material 10% 28 days old (71,612kg/cm2<350kg/cm2), and a decrease in the compressive strength of concrete with a variation of 15% is (9,69kg/cm2<350kg/cm2). From the results of the compressive strength test it can be concluded that the use of aluminum powder substitute materials can not increase the compressive strength of the concrete and instead make the concrete become brittle. The value of concrete slump decreases with increasing levels of use of substitute materials. The biggest slump value obtained is 11 cm in normal concrete with 0% level. From the results of the compressive strength test it can be concluded that the use of substitute materials can not increase the level of ease of work or concrete workability.
