Performance Evaluation of M30 Grade Concrete Using Silica Sand as Partial Replacement of Cement in Concrete

Abstract

Abstract: This study explores the improvement of concrete parcels, particularly strength and continuity, through the partial substitute of cement with silica fume (SF). The exploration addresses the environmental and health issues caused by artificial waste disposal, similar to covering ash and copper slag, by incorporating silica sand into concrete. A literature review reveals that SF significantly improves the mechanical and continuity characteristics of concrete, enabling the product of highperformance concrete suitable for these soundings. This paper investigates the strength parameters of concrete with 0 –15% SF relief in increment of 5%, comparing the results with conventional concrete. Findings indicate that the optimal compressive strength and split tens are achieved at 10% SF relief, beyond which strength decreases. This study aims to inform civil masterminds about the benefits of SF- modified concrete composites.
