Abstract

This study uses an experimental method to investigate the behavior of concrete blocks coated with fiber paint, focusing on their shear and flexural strength, ductility, stiffness, and energy dissipation to enhance their mechanical performance. The fiber paint coatings used in this study were applied in different thicknesses, namely 1 mm, 2 mm, and 3 mm. The results show that a 3 mm coating provided the highest improvement, with shear and flexural strengths increasing by 47.36% and 66.06%, respectively. Flexural ductility improved by up to 32%, while stiffness increased by 12% in flexure and 13% in shear. Energy dissipation also showed significant enhancement; total flexural energy increased from 1.38 kNmm to 10.76 kNmm at 3 mm, and shear energy dissipation reached 50.72 kNmm at 3 mm. These results confirm that fiber paint can enhance the shear and flexural strength, ductility, stiffness, and energy dissipation of concrete blocks. This study introduces fiber paint as a practical reinforcement method for concrete block materials, offering a simple, easy-to-apply, and cost-effective alternative that improves both mechanical and aesthetic performance.

Abstract

The construction industry significantly contributes to global carbon emissions, driving the urgency for sustainable and eco-friendly wall material innovations. This study aims to map the trends and evolution of literature regarding sustainable wall material innovations using a bibliometric analysis approach from 2016 to 2026. The research employs a descriptive quantitative method by extracting article metadata from the Google Scholar database using Publish or Perish software. The filtered final data was then analyzed using VOSviewer to generate Network Visualization, Overlay Visualization, and Density Visualization. The network analysis results indicate that global literature is still dominated by the utilization of recycled materials and waste bricks as macro-aggregate substitutes, while regional studies using local terminology remain in peripheral areas. Based on the evolutionary analysis, research trends exhibit a measurable shift from macro-mechanical strength testing toward micro-level material engineering, encompassing the use of alternative precursors and hydration kinetics behavior. Furthermore, the density mapping identified highly potential research gaps in the topics of hydration kinetics, modified thermal property evaluation, and pore maker optimization. These findings conclude that the future direction of sustainable construction material development should not solely focus on structural strength but must integrate micro-chemical interaction analysis and thermal insulation performance to comprehensively support building energy efficiency.

Abstract

Paving block is a surface pavement material widely used in Indonesia for residential, commercial, and public facility areas. The quality of paving block is largely determined by the composition of its constituent materials, particularly the cement-to-sand ratio as the main components. This study aims to analyze the effect of variations in cement and sand mixture on the compressive strength of paving block based on a Systematic Literature Review (SLR) from various published scientific sources. From the compiled literature, it was found that mixtures with a cement:sand ratio of 1:3 to 1:4 produced the highest compressive strengths of 35-45 MPa, meeting Grade A standards based on SNI 03-0691-1996. Conversely, mixtures with a ratio of 1:7 and above produced compressive strengths below 15 MPa, suitable only for limited use. The water-cement ratio (w/c) also plays a significant role: the higher the w/c ratio, the lower the resulting compressive strength. These findings confirm the importance of optimizing mixture proportions in producing paving blocks that meet national quality standards.

Abstract

Heavyweight concrete is a specialized construction material widely used in facilities requiring protection against ionizing radiation and the ability to withstand high structural loads. The primary characteristics of heavyweight concrete are determined by the use of high-density aggregates such as barite, magnetite, hematite, ilmenite, limonite, and serpentine, each offering distinct advantages and limitations in terms of mechanical performance, durability, and radiation shielding capability. This study aims to analyze and compare various types of heavyweight aggregates used in heavyweight concrete and evaluate their influence on the mechanical properties and long-term durability of concrete. The research employed a Systematic Literature Review (SLR) approach using the PRISMA framework. A total of 15 scientific articles published between 2020 and 2026 were selected from Scopus and Google Scholar databases. The review process consisted of identification, screening, selection, and synthesis stages based on their relevance to heavyweight aggregates, concrete mechanical properties, durability, and radiation shielding performance. The findings indicate that magnetite and hematite exhibit superior mechanical performance, characterized by higher compressive strength and elastic modulus values, while barite demonstrates the most effective gamma-ray attenuation capability. Ilmenite provides excellent resistance to aggressive environments containing sulfates and chlorides, whereas limonite and serpentine are particularly effective for neutron shielding due to their hydrogen-rich composition. In the Indonesian context, magnetite and ilmenite emerge as the most promising alternatives because of their abundant local availability and competitive technical performance. This study concludes that the selection of heavyweight aggregates should simultaneously consider structural requirements and radiation protection demands. Furthermore, hybrid formulations combining multiple heavyweight aggregates offer significant potential for optimizing the overall performance of heavyweight concrete and represent a promising direction for future infrastructure and nuclear-related applications.
