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...

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...

Main conclusion Optimizing environmental factors can significantly increase the growth and secondary metabolite synthesis of hydroponically grown medicinal plants. This approach can help increase the quality and quantity of pharmacologically important metabolites to enhance therapeutic needs. Abstract Medicinal plants are key therapeutic sources for treating various ailments. The increasing demand for medicinal plants has resu...

The research proposes the introduction of helices into the very popular reinforced cement concrete (RCC) piles to enhance the soil–pile interaction. The behavior of RCC helical piles under combined axial and lateral loading are reported. A 3D finite element model is developed using Abaqus software to simulate the pile–soil interaction. Steel helical piles have gained popularity due to their ease of installation and higher load...
