Properties of concrete containing fly ash and bottom ash mixture as fine aggregate
About one-fifth of coal ash produced by the thermal power plants are the bottom ash, and the rest is fly ash. During the past few decades, studies are made to use either of them as the partial replacement of sand in concrete manufacturing.

This study assessed toxic metals in five dried marine fish species from Bangladesh. Although most metals were within safe limits, chromium (Cr) consistently exceeded FAO/WHO standards, especially at Kuakata Beach. The findings highlight localized contamination hotspots and species‐specific bioaccumulation, while risk assessment supports the safety and ...
