Concrete structures in coastal–industrial regions are simultaneously exposed to acid rain, carbonation, and chloride ingress; however, most durability studies investigate these mechanisms independently, limiting realistic service-life prediction. This study presents an integrated experimental, statistical, and artificial neural network (ANN)-based evaluation of M40-grade concrete subjected to synthetic acid rain, accelerated c...

As anthropogenic disturbance restructures ecological communities worldwide, ecologists have developed and tested hypotheses about which species “win” and “lose” in the face of human impacts. One heavily invoked paradigm is that of the human shield, which posits that predators avoid areas of human disturbance due to perceived risk from humans, and prey therefore seek refuge in these areas of perceived safety. Since its introduc...

Concrete pavements are renowned for their ability to handle heavier loads and lower life cycle costs than flexible pavements. Fibers into concrete further enhance its durability by reducing maintenance and rehabilitation costs. This study investigates the fatigue performance of pavement quality concrete (PQC) M40-grade reinforced with polyolefin fibers, focusing on structured fibers (SF) and twisted fibers (TF). Polyolefin fib...
