Subject:
concrete; construction materials; durability; ecosystems; industrial byproducts; industrial wastes; infrastructure; life cycle assessment; mechanical properties; microstructure; mining; raw materials; rivers; sand; social benefit; stream channels
Abstract:
... Construction sector is mainly liable for waning of natural resources and environmental imbalances due to its unplanned mining activities. The massive use of concrete due to boom in various infrastructure development has led to over-extraction of river sand from the riverbed. This has called for several harmful consequences of ecosystem and non-availability of good quality of raw materials. Disposa ...

Abstract:
... Impermeable materials are used for parking lots at apartment complexes and large stores which are concentrated in urban areas. These materials increase the amount of surface runoff by blocking infiltration, resulting in flood damage, dry stream phenomena in rivers in urban watersheds, and the depletion of ground water. In this study, a parking lot plot was constructed to quantitatively evaluate th ...

... To evaluate the effects of water velocity and artificial substratum characteristics on the growth rate and biomass accumulation of periphyton, an artificial stream mesocosm experiment was conducted using alternative water sources collected from the Mangwall Stream (MW), the Han River (HR), and bank filtration water (BFW) from the Han River in the Republic of Korea. The measured concentrations of o ...
