Mechanical Enhanced Involuntary Stress-Strain Characteristics and Environmental Assessment: GGBS & Silica-Fume

Abstract

The research looks at the characteristics of Normal Concrete (NC) by testing small square blocks and larger cylindrical samples to see how they respond under pressure and strain. The flexibility of different Ground Granulated Blast Furnace Slag (GGBS) and silica fume mixtures is measured using the Saenz Model, and the results are shown in graphs comparing stress and strain. This study examines how substituting materials like GGBS and adding materials like silica fume to concrete affects its strength and environmental impact. Seven mix designs of M35 grade concrete were prepared to study strength, toughness, ability to stretch, and absorb energy, and how stress and strain are related. The results show that substituting 35% GGBS and adding 10% silica fume is best for improving the strength of NC when compressed. The suggested mathematical equations for how well NC can resist being compressed match up closely with the real-life test results. However, the measured factors show that incorporating 30% GGBS with 5% and 15% silica fume in the concrete causes more environmental harm. However, the NC without pozzolana shows a lower measure of its environmental impact, except for its contribution to climate change.
