“…Untuk konstruksi perkerasan jalan, paving block dapat menjadi alternatif ekonomis dan paving block juga memiliki kekuatan, daya tahan serta estetika yang indah untuk permukaan sehingga dapat diterapkan di daerah komersial, kota dan industri seperti area parkir, wilayah pejalan kaki, persimpangan lalu lintas dan jalan (El Nouhy, 2012) Penelitian bahan tambah material buatan pada paving block sudah diteliti, seperti pada penelitian (Adibroto, 2014) dengan penambahan serat ijuk, plastik dan kawat, penelitian (Kusuma, 2012) dengan pemanfaatan limbah kulit kerang sebagai bahan campuran paving block serta penelitian (Dewi dan Mahyudin, 2018) melakukan analisis sifat fisis dan ketahanan terhadap natrium sulfat paving block dengan variasi serbuk cangkang langkitang dan penambahan serat ijuk.…”

Abu ketel dan ampas tebu memiliki perbedaan dalam stuktur fisiknya, oleh karena itu pengelolaan dan pemanfaatannya juga terbatas. Pada Pabrik Gula Kremboong kapasitas penggilingannya adalah 2700 ton/hari. Produksi gula yang cukup tinggi juga berdampak pada limbah pabrik yang dihasilkan. Limbah abu yang dihasilkan setiap harinya tidak kurang dari 115 kwintal. Plastik merupakan limbah yang akan terus menjadi permasalahan lingkungan apabila tidak tertangani secara baik. Paving block sering digunakan untuk jalan dengan perkerasan kelas ringan, trotoar, taman, dan penutup permukaan yang fungsinya masih mampu menyerap air di permukaan. Paving block banyak digunakan karena kemudahan dalam pemasangan dan perawatannya. Salah satu alternatif penanganan limbah padat yang dapat dilakukan adalah dengan memanfaatkan abu ketel menjadi campuran paving blok, dengan variasi menggunakan penambahan limbah plastik. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif eksperimen. Pengaruh penambahan limbah abu ketel dan limbah plastik terhadap kemampuan penyerapan air pada paving block cukup berpengaruh. Dan pada penyerapan air paving block menunjukkan variasi campuran 5% dan 7% dengan hasil dibawah 2%, ini memenuhi persyaratan mutu paving block sesuai SNI 03-0691, 1996.

This article describes how in developing countries, millions of tons of construction and demolition wastes (CDWs) are lost every year due to lack of knowledge of recycling significance and/or procedures. Despite the high value of CDWs, high percentage of this waste is either dumped illegally or disposed in the landfills. Disposal methods should consider saving natural resources and maintaining the environmental conditions through maximizing the value of CDWs. This article aims at choosing the most sustainable disposal alternative using Multi-Criteria Decision Making (MCDM) Process, considering several sustainability measure indicators. The research introduces a list containing the most relevant and significant sustainable indicators that affect the selection of alternative for disposal of CDWs. Then, fuzzy TOPSIS technique is applied considering the significant indicators on each alternative to rank and choose the best alternative for disposal of CDWs.

“…It helps in reducing greenhouse gas emissions and conserving natural resources. Thus, the use of slag cement in concrete can be treated as 'Green Concrete' from the environmental point of view as it utilizes the waste by-product from iron-manufacturing industries [16]. PSC has better performance when compared to OPC, such as long-term strength development due to alkali-silica reactions, enhanced overall strength and durability, increased resistance to chemical attack, and improved resistance to sulfate and chloride ingress, and is environmentally friendly.…”

The demand for sustainable construction materials has driven the exploration of various innovative approaches to enhance the properties of concrete for reducing its environmental impact. The present study examines the effects of incorporating recycled concrete aggregate (RCA), slag cement, alccofine, and glass fibers into concrete mixtures. In the present study, it has been observed that recycled concrete aggregate (RCA) exhibits inferior properties, including higher water absorption and poorer performance, when compared to natural coarse aggregate. Various replacement levels of RCA were utilized in this study to assess its impact on concrete performance. Alccofine, a supplementary cementitious material, is used to partially replace the binding material. Additionally, glass fibers were added to enhance the flexural and tensile behavior of the concrete. The concrete mixtures were designed to meet the required strength and durability specifications. A comprehensive testing program was conducted to evaluate the fresh and hardened properties of the concrete. A slump cone test was performed for assessing the workability of fresh concrete. For hardened concrete, compressive strength, flexural strength, and split tensile strength are evaluated. The results demonstrated that incorporating RCA, slag cement, alccofine, and glass fibers into the concrete mixtures improved mechanical properties. The use of RCA led to a reduction in natural resource consumption, namely natural coarse aggregate in concrete. On the other hand, the generated construction and demolition (C&D) waste is used effectively. Portland slag cement (PSC) and alccofine (A) improved the long-term strength of concrete. The addition of glass fibers significantly enhanced the tensile and flexural performance of the concrete, resulting in improved crack resistance and overall performance. This study introduces a novel concept by exploring the potential utilization of recycled concrete aggregate, slag cement, alccofine, and glass fibers in combination as sustainable and high-performance components in concrete mixtures. Previous research has not extensively studied this combination of materials, making it a unique and innovative approach. These findings contribute to the development of eco-friendly construction practices and provide insights for engineers, researchers, and practitioners aiming to incorporate recycled materials and supplementary cementitious materials into concrete construction.
