PENGARUH PENGUNAAN PASIR POZZOLAN SEBAGAI SUBSTITUSI AGREGAT HALUS TERHADAP KUAT TARIK BELAH, KUAT TARIK LENTUR DAN KUAT GESER MURNI BETON MUTU TINGGI [PDF]

, 2016
Beton mutu tinggi memiliki rasio kekuatan terhadap berat (strength to weight Ratio) yang sangat kecil, oleh karna itu digunakanlah pasir pozzolan sebagai substitusi agregat halus karena pasir pozzolan memiliki berat jenis lebih kecil daripada pasir beton

Stone‐Cutting Dust as a Sustainable Supplementary Cementitious Material: A Comprehensive Review of Its Physicochemical and Mechanical Effects

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Ordinary Portland cement (OPC) remains the most common binder used in construction and accounts for nearly 7%‐8% of the world’s CO2 emissions due to calcination of limestone and high energy use during clinker production. Reducing OPC content using SCMs is one of the major strategies to achieve sustainable construction.

Advanced Applications of Pozzolan-Derived Silica: Hydrophobic Agent Synthesis

Jurnal Rekayasa Kimia & Lingkungan
The Sumatera Barat province of Indonesia, particularly Padang Pariaman Regency, is rich in pozzolan, a natural resource characterized by high silica (SiO₂) and alumina (Al₂O₃) content. Despite its abundance, pozzolan remains underutilized, primarily used

The workability, mechanical, and electrical properties of steel fiber‐reinforced SCC incorporating ultra‐fine copper slag as fine aggregate

Structural Concrete, Volume 26, Issue 6, Page 7571-7590, December 2025.
Abstract Ultra‐fine copper slag (CS), a byproduct of the copper industry, is al waste material that is produced in large volumes annually, and its disposal and management are a major environmental concern. Therefore, the utilization of CS in various sectors, especially in the production of construction and building materials, offers enormous potential ...

Transformation of a Silicate Material for Carbon Negative Magnesia‐Based Cement via Electrochemistry

Advanced Science, Volume 12, Issue 42, November 13, 2025.
The transformation of a magnesium trisilicate material via water electrolysis into precursor phases necessary for magnesium‐based M‐S‐H cement is explored. The dissolution of the material mediated electrochemically is monitored, and the analysis of the resulting phases indicate their suitability as effective precursors for M‐S‐H cement.

Thermally treated granite slurry waste as a mitigating agent for sisal fiber mineralization in fiber‐cement composites

International Journal of Applied Ceramic Technology, Volume 22, Issue 5, September/October 2025.
Abstract This study explores the use of thermally treated granite slurry waste to mitigate the mineralization of sisal fibers in fiber‐cement composites. Granite waste was thermally treated at 600°C and 900°C, and the treated materials were analyzed using X‐ray fluorescence (XRF), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric ...
