The building sector consistently pursues sustainable and economical substitutes for traditional materials. This study investigates the feasibility of utilizing stone dust as a partial substitute for fine aggregates in the production of interlocking paver blocks. The main aim is to assess the fresh and mechanical characteristics of paver blocks by altering the ratios of stone dust. The research concentrates on mix designs in which stone dust substitutes 0–40% of fine aggregates by weight in the formulation of M30 grade concrete. Paver blocks with a thickness of 60 mm are reengineered and evaluated based on workability, compressive strength, and flexural strength assessments. Findings demonstrate that the inclusion of stone dust improves both compressive and flexural strength to a specific substitution threshold. Consequently, identifying the ideal stone dust content is crucial for attaining a balance between workability and strength in concrete applications.

摘要

The building sector consistently pursues sustainable and economical substitutes for traditional materials. This study investigates the feasibility of utilizing stone dust as a partial substitute for fine aggregates in the production of interlocking paver blocks. The main aim is to assess the fresh and mechanical characteristics of paver blocks by altering the ratios of stone dust. The research concentrates on mix designs in which stone dust substitutes 0–40% of fine aggregates by weight in the formulation of M30 grade concrete. Paver blocks with a thickness of 60 mm are reengineered and evaluated based on workability, compressive strength, and flexural strength assessments. Findings demonstrate that the inclusion of stone dust improves both compressive and flexural strength to a specific substitution threshold. Consequently, identifying the ideal stone dust content is crucial for attaining a balance between workability and strength in concrete applications.
