Abstract

Self-Compacting Concrete (SCC) is an innovation in concrete technology used in building elements with dense and complex reinforcement frameworks. SCC is characterized by its high fluidity and the ability to self-compact without the use of vibrators. Superplasticizer is one of the components applied in the production of SCC. The use of superplasticizer aims to reduce water consumption, accelerate the setting time, improve concrete workability, and also make the concrete impermeable. As time progresses, industrial waste continues to increase, highlighting the importance of recycling industrial waste. The purpose of this research is to investigate the influence of industrial waste as a substitute material for fine aggregates on the workability and compressive strength of SCC. This study is the result of a literature review obtained by examining various sources including books, proceedings, as well as international and national journals. The results of this literature study involve the use of industrial waste materials such as recycled glass, granite waste, nickel slag, and copper slag as substitutes for fine aggregates. The results of the workability and compressive strength of SCC are influenced by the characteristics of each industrial waste used. This indicates an improvement in the flowability (slump flow) with an increasing percentage of industrial waste, ranging from 0% to 60%, in the concrete composition. Compressive strength test results indicate that the optimal percentage of industrial waste addition in the concrete composition lies between 20% and 40%."

Abstract

Perkembangan pembangunan infrastruktur di Indonesia  yang semakin meningkat akan berdampak pada meningkatnya permintaan akan material konstruksi. Material konstruksi yang berasal dari alam dan dieksploitasi terus menerus untuk memenuhi kebutuhan pembangunan pada akhirnya akan habis dan dapat merusak ekosistem di sekitarnya. Terak nikel merupakan limbah padat dari peleburan bijih nikel. Jumlah terak nikel yang semakin banyak karena limbah yang dihasilkan 50 kali lebih banyak dari produk nikel yang dihasilkan. Secara visual, terak nikel menyerupai kerikil dan pasir dapat digunakan sebagai material alternatif. Penelitian ini adalah hasil studi pustaka mengenai pemanfaatan terak nikel sebagai penganti sebagian agregat pada beton mutu tinggi. Metode yang digunakan dalam penelitian ini adalah studi literatur yang bersumber dari buku, prosiding, jurnal-jurnal internasional maupun nasional yang bereputasi Q1-Q4. Hasil dari penelitian ini menunjukkan bahwa terak nikel dapat digunakan sebagai agregat halus maupun kasar pada beton hingga kadar 100%, namun untuk mendapatkan kekuatan maksimal penggunaan terak nikel hanya sampai 40%, melebihi persentase tersebut kekuatan dari beton tersebut akan menurun. Keywords : High strength concrete, nickel slag, compressive strength
