Recycled Aggregate Concrete Performance

Post-earthquake permanent housing should not be understood merely as the rapid provision of shelter, but as a multi-stage reconstruction process that must address resilience, adaptability, resource efficiency, and long-term environmental performance. Although the circular economy offers a strong conceptual framework f…

Sanayileşme ve tüketim artışıyla birlikte artan atık miktarı, doğal kaynakların tükenmesine ve yaşam kalitesinin düşmesine neden olmaktadır. Bu bağlamda, atık malzemelerin geri dönüştürülerek yapı sektörüne entegre edilmesi, sürdürülebilirlik hedefleri açısından kritik bir öneme sahiptir. Ancak mevcut literatür incele…

Abstract This study evaluates the mechanical, durability, statistical, and environmental performance of recycled aggregate concrete (RAC) incorporating volcanic ash (VA) as a partial cement replacement and basalt (BA) fibers as reinforcement. VA was used at 5%, 10%, and 15%, followed by BA fiber additions of 0.25%, 0.…

Abstract The durability of concrete is a crucial factor in the lifespan, serviceability, and sustainability of infrastructure throughout its life cycle. This analysis analyzes the primary degradation mechanisms of concrete, including freeze-thaw damage, sulfate and acid attack, carbonation, and alkali-silica interacti…

Sürdürülebilirlik, günümüzde yapı sektöründe giderek daha fazla önem kazanmaktadır. Son yıllarda inşaat sektörü, çevresel etkileri azaltmak ve yapı malzemelerinin üretiminde kullanılan doğal kaynak tüketimini minimize etmek amacıyla sürdürülebilir ve çevre dostu malzeme alternatiflerine yönelmektedir. Bu araştırmada,…

Subterranean metro stations require substantial structural material inputs and can generate prolonged disruption in dense urban environments. Rather than assessing the environmental performance of an entire metro system, this study compares the embodied environmental impacts and surface-occupation effects of two repre…

The reliable prediction and sustainable optimization of the compressive strength (CS) of recycled aggregate fiber-reinforced self-compacting concrete (RA-FRSCC) represent significant challenges in modern concrete engineering, primarily because of the intricate and highly nonlinear relationships among mix-design parame…

The accurate prediction of compressive strength (CS) is a fundamental requirement for structural safety, yet conventional empirical models remain limited in their ability to capture the complex nonlinear response of cementitious materials. Hybrid machine learning (ML) and deep learning (DL) models are investigated for…

Asphalt pavement is used extensively on highways today. However, these coatings are affected by environmental conditions and vehicle loads and thus complete their service life. Incorporating Recycled Asphalt Pavement (RAP) as a fine aggregate (0–4 mm) in concrete, replacing crushed sand, reduces natural aggregate dema…
