In a groundbreaking study published in ‘Jurnal Teknik Hidraulik,’ researchers have unveiled the potential of using steel slag as a substitute for gravel in concrete applications, specifically for sabodam, a type of dam used to manage sediment retention. This innovative approach not only addresses the environmental challenge posed by the abundance of steel slag but also offers promising benefits for the construction industry.
Steel slag, a byproduct of the iron and steel smelting process, has long been viewed as a waste material. However, Jati Iswardoyo, the lead author of the study, emphasizes the importance of reimagining this resource. “By utilizing steel slag in construction, we can significantly reduce waste while enhancing the durability of concrete structures,” Iswardoyo stated. The research highlights that concrete made with steel slag demonstrates superior compressive strength compared to traditional concrete using split stones, especially under flood conditions.
The study meticulously analyzed the stability of sabodam structures, employing the SNI 2851: 2015 standards for sediment retention building design. The findings revealed that sabodam constructed with steel slag exhibited a minimum bearing capacity of 1.74 kN/m2 during flood scenarios, compared to a mere -0.98 kN/m2 for those using split stones. This significant difference indicates that concrete with steel slag not only withstands the demands of environmental stresses but also remains structurally sound without succumbing to tensile stresses.
This research holds substantial commercial implications for the construction sector, particularly as sustainability becomes a key focus in building practices. The ability to repurpose steel slag not only reduces reliance on natural gravel but also aligns with global efforts to minimize waste and promote eco-friendly construction materials. As Iswardoyo articulated, “This is not just about improving concrete; it’s about reshaping our approach to construction and sustainability.”
The potential for this innovative use of steel slag extends beyond sabodam. It opens doors for broader applications in various concrete structures, potentially revolutionizing how the industry views waste materials. As the construction sector grapples with increasing environmental regulations and a push towards greener practices, studies like this pave the way for more sustainable solutions.
As the construction landscape evolves, the insights from Iswardoyo’s research could lead to significant advancements in material science and engineering practices. The integration of steel slag into mainstream construction could not only enhance structural integrity but also contribute to a circular economy within the industry.
