Abstract

Penggunaan produk baja sebagai bagian dalam struktur bangunan untuk konstruksi dalam negri semakin meningkat. Salah satu dampak operasional industry peleburan logam baja adalah besarnya jumlah limbah yang berupa slag yang dihasilkannya. Hal ini disebakan oleh kandungan logam didalam biji yang relatif kecil. Apabila slag yang dihasilkan tidak dikelola dengan baik, maka akan dapat menimbulkan masalah bagi lingkungan, sehingga slag perlu mendapatkan penanganan yang tepat. Inovasi pembuatan beton dengan penggunaan limbah, masih akan terus dikembangkan. Salah satu inovasi yang dilakukan adalah dengan memanfaatkan Iron slag sebagai bahan substitusi sebagian agregat halus. Penelitian ini bertujuan untuk mengetahui bagaimana kekuatan beton setelah menggunakan bahan tersebut.Penelitian dilaksanakan di Laboratorium Struktur dan Bahan Beton Jurusan Teknik Sipil Universitas Bosowa. Benda uji dibuat dalam 2 (dua) tipe yaitu beton normal (beton kontrol) dan beton variasi Iron slag. Iron slag digunakan sebagai material substitusi agregat halus dengan memvariasikan kadarnya dalam campuran beton sebesar 0%, 75% dan 100% dan penggunaan Superplasticizer sebanyak 1%. Benda uji akan diamati pada umur 28 hari, dimana jumlah benda uji sebanyak 29 buah. Data yang terkumpul digunakan untuk menganalisis karakteristik beton yang menggunakan Iron slag.

Abstract

The purpose of this study was to analyze the properties and characteristics of the warm mixture of emulsified asphalt and to analyze the effectiveness of the characteristics of the warm mixture of emulsified asphalt with variations of immersion. The independent variable in this study is the immersion variation. The test method refers to the General Specifications of Highways 2018. The type of mixture used is Asphalt Concrete - Wearing Coarse. The performance was measured by testing Density, Stability, Flow, Marshall Quontient, voids in mixture (VIM), voids filled with asphalt (VFB), and voids in aggregate (VMA). The asphalt content used was 6.5%, then repeated immersion was carried out with variations of 3 days, 7 days, and 14 days of immersion. The results showed that the use of a warm mixture of emulsified asphalt and the length of immersion time affected the decrease in the value of the asphalt mixture properties. This is because the longer the immersion the asphalt adhesion to the mixture will decrease and the chance of losing the durability or durability of the mixture is also getting bigger. And from the results of the Marshall test using a warm mixture of asphalt emulsion, the best value for the characteristics is 3 days of immersion. Because it has a higher stability value so it will be able to withstand a greater load
