APL008-3-8 Effect of GGBFS on Compressive Strength and Durability of Concrete
Abstract
This research examines the impact of incorporating Ground Granulated Blast Furnace Slag (GGBFS) at 4%, 6%, and 10% as partial cement replacement on concrete compressive strength and durability. Findings showed moderate early-age strength gains, with significant improvements at extended curing periods. Concrete with 10% GGBFS achieved the highest compressive strength, attributed to enhanced pozzolanic reactions and refined microstructure. Additionally, GGBFS improved concrete durability against chloride penetration and sulfate attack, highlighting its potential for sustainable construction practices by reducing cement use and lowering environmental impact, supporting global sustainability goals [1][5].
