Evaluation of Compressive Strength of Concrete Using Fly Ash, Silica Fume, and Steel Slag as Cementitious and Aggregate Replacements
Abstract: This study comprehensively investigates the influence of supplementary cementitious materials and industrial by-products—specifically fly ash, silica fume, and steel slag—on the compressive strength of concrete. The primary objective is to evaluate the impact of both individual and combined replacements of cement and aggregate components on concrete performance. The research analyzes how varying proportions of these materials affect the strength characteristics of the concrete mixtures. Experimental results demonstrate that increasing the …

Combine Effect of Metakaolin, Recycled Steel Fiber and Waste Glass Powder on Mechanical Properties of Concrete
Abstract: This study investigates the combined effects of metakaolin, recycled steel fiber, and waste glass powder on the mechanical properties of concrete. Specifically, the research explores concrete mixes with metakaolin, crushed glass powder at 9%, 12%, 15%, and 18%, and recycled steel fiber at 0.5%, 1%, 1.5%, and 2% as partial replacements for cement. The primary aim is to identify the optimal mix proportions that enhance the compressive strength, flexural strength, …
