Abstract
Now days, Nanotechnology is introduced in civil industry for ceramics, composites, and mortar to achieve better performance in different mechanical parameters of these materials. At the same time, Environment prevention is pin point for the civil industry because of cement production. As a solution of better performance of structural materials with environment prevention, steel making industry waste powder at Nano-scale giving better enhanced strength of mortar. This research work introducing the acceptable partial replacement of the steel waste powder in place of ordinary Portland cement to minimize environmental pollution due to cement production considering waste disposal solution. In the mortar making process, pure steel making waste used in powder form having compositions of SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, Sulphide, Na2O3, K2O, Cl and MnO. Combined effect of these all compositions greatly affected on the mechanical properties of mortar containing this waste powder. To know the effect of this waste powder containing all these compositions in mortar, different mechanical parameters of mortar like compression, tension, flexural, shear and impact test were performed. For this innovative approach, steel making industry waste powder was examined to set consistency for mortar making purpose. To get optimum dosage of waste powder, 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, and 90% replacement were done in place of cement. Physical parameters like Compressive, Tensile and Flexural, Shear and Impact strength were examined using optimum dosage of waste powder. This innovative research work introduced the enhanced strength after 3 days, 7 days and 28 days curing. From this research work, it is advisable to use mortar containing waste powder in load bearing structures which is giving sustainable waste disposal solution including CO2 reduction in environment.
