DESTRUCTIVE AND NON-DESTRUCTIVE PERFORMANCE OF CONCRETE CONTAININGALCCOFINE AS A PARTIAL CEMENT REPLACEMENT

Abstract

Worldwide concrete production significantly contributes to environmental degradation due to the emission of greenhouse gases from cement production and imbalances of the ecosystem due to the continuous diminution of natural resources. This study investigates a sustainable alternative by using Portland Slag Cement incorporating Alccofine as a partial cement replacement at varying proportions (0%–20%). The mixes were prepared for a relatively higher M40 grade structural concrete with a w/c ratio of 0.36. Mechanical properties were evaluated through non-destructive tests after curing. Outcomes show that a 15% Alccofine yields the highest enhancement in mechanical performance, outperforming traditional concrete. Alccofine high pozzolanic reactivity and fineness contribute to better early-age strength and durability. This study presents a novel, synergistic approach to producing high- performance, eco-friendly concrete, offering a practical solution for reducing constructional hazards and environmental impact while supporting sustainable construction practices.
