Development of lightweight structural concrete with artificial aggregate manufactured from local clay and solid waste materials.

The partial replacement of conventional natural coarse aggregate (NCA) with artificial light weight aggregate (LWA) manufactured from local clay and solid waste to develop a lightweight aggregate concrete (LWAC) for the structural use was studied in this paper. Red clay and Savar clay were used individually with solid wastes like rice husk ash (RHA) and waste glass to produce LWA. The suitability of raw materials and LWA was evaluated by investigating various properties.

Parameters optimization of FeO NPs synthesis by leaf extract possessing both peroxidase as well as excellent dye removal activity.

This study reports optimized conditions for the green synthesis of iron (II,III) oxide nanoparticles (FeO NPs) from leaf extract. The synthetic parameters like concentration of leaf extract, solvent system, buffer, electrolyte, pH, and time were optimized for FeO NPs synthesis. FeO NPs were obtained from the synthesis protocol by measuring size (80 3 nm approx.
