| چکیده | ||
| This study is focused on evaluating the behaviour of use of alternatives for cement, namely, Ground-Granulated Blast Furnace Slag (GGBS) and Nano Silica (NS), on the the mechanical, microstructure, and structural behavior of in reinforced concrete (RC) slabs. Concrete was made with various dosages of GGBS from 0% to 50% at a rate of 5% and NS dosage from 0.1% to 1% at an interval of 0.1%. Compressive and tensile strength of concrete was evaluated along with microstructural characteristics using Scanning Electron Microscopy (SEM). The optimum dosages ware found to be 10% GGBS and 0.3% NS by cement weight. This optimum dosage, was used in making RC slabs with dimensions 1200 x 1200 x 100 mm, varying the slab thickness. To determine the stiffness and load-bearing capacity of the slabs, two-point loading was applied. Use of GGBS and NS results in high-density and high- strength concrete. Such research works highlight the prospective use of GGBS and NS in sustainable construction, encouraging cost-effective, eco-friendly practices with innovations in concrete technology. | ||
