EVALUATION OF STRENGTH PROPERTIES OF FERRO GEOPOLYMER WRAPPED CONCRETE SPECIMENS

Main Article Content

Abstract

Built up substantial designs in chilly regions frequently weaken right on time because of steel erosion. Fiber-Supported Concrete (FRC) offers a practical choice to upgrade strength and break opposition. This study looks at hybrid ferro fiber-reinforced concrete slabs that use spot-welded mesh, polypropylene fibers (PPF), and silica fume in varying proportions in a mortar mix (1:2). A control RCC slab (1:2:4) and ferrocement slabs with 0.10%, 0.30%, and 0.50% PPF were among the thirteen one-way slabs tested. The steel proportion in ferrocement sections shifted from 25% to 100 percent of the control chunk's steel region. Under third-point loading, deflection, stress-strain behavior, cracking load, and energy absorption were used to evaluate structural performance. When compared to the RCC control slab, the results showed that slabs with 0.5% PPF and 10% silica fume had a 15.25 percent increase in first cracking load and a 13.2% increase in ultimate deflection. This suggests that slabs with higher PPF and steel mesh reinforcement had better post-cracking behavior and were better able to absorb energy.
