Abstract

Bu çalışma, Geri Dönüştürülmüş Asfalt Kaplaması (RAP) ve kaba agregaların sürdürülebilir inşaatlardaki rolüne odaklanarak, Enerji Dağılımlı X-Işını Floresansı (EDXRF) kullanarak kapsamlı bir elemental analiz yapmaktadır. SiO₂, Al₂O₃, CaO, CuO ve ZnO gibi elementler analiz edilerek beton dayanımı, dayanıklılığı ve genel performans üzerindeki önemli etkileri ortaya konulmuştur. RAP, elle işlenmiş ve Gboko Yerel Yönetim Alanı'ndaki Mkar tepesinden alınan agregalarla birleştirilmiştir. Bulgular, %50 RAP ikamesi ile yapılan beton karışımlarının en yüksek basınç dayanımına ulaştığını, %75 RAP ikamesine sahip karışımların ise yarma çekme ve eğilme dayanımında üstün performans gösterdiğini ortaya koymaktadır. Bu sonuçlar, RAP'ın mekanik özellikleri geliştirmedeki etkinliğini vurgulamakta ve çevre dostu altyapı geliştirilmesinde kullanımının artırılması gerektiğini savunmaktadır.

Energy Dispersive X-Ray Fluorescence (EDXRF)- Oxide Composition Analysis of Coarse Aggregates and Reclaimed Asphalt Pavement (RAP) as Construction Materials

Abstract

This study utilizes Energy Dispersive X-Ray Fluorescence (EDXRF) to conduct a detailed elemental analysis of Recycled Asphalt Pavement (RAP) and coarse aggregates, focusing on their role in sustainable construction. Elements such as SiO₂, Al₂O₃, CaO, CuO, and ZnO were analyzed, revealing their significant influence on concrete strength, durability, and overall performance. RAP was manually processed and combined with aggregates from Mkar hill in Gboko Local Government Area. The findings show that concrete mixes with 50% RAP replacement achieved the highest compressive strength, while those with 75% RAP replacement excelled in split tensile and flexural strength. These results highlight RAP's effectiveness in enhancing mechanical properties, advocating for its increased use in eco-friendly infrastructure development.
