Performance Analysis of Self-Curing Concrete Using Stone Dust as Partial Fine Aggregate Replacement

Key Points

The primary aim is to analyze how stone dust affects the performance of self-curing concrete while substituting fine aggregates.
Test various proportions of stone dust (0%, 10%, 20%, 30%, 40%, and 50%) as a fine aggregate replacement.
Assess fresh and hardened concrete properties like workability, compressive strength, water absorption, and durability.
Compare performance metrics at different replacement levels.
Stone dust improves workability and compressive strength up to an optimal replacement level.
Beyond the optimal percentage, the performance of concrete diminishes.
Using stone dust not only enhances concrete properties but also provides environmental benefits by reducing waste.

Abstract

This research examines the performance of self-curing concrete incorporating stone dust as a substitute for fine aggregates. SCC is increasingly used due to its ability to maintain internal moisture without requiring external water curing, making it suitable for water-scarce regions. Stone dust, an industrial waste material, is utilized in different proportions (0%, 10%, 20%, 30%, 40%, and 50%) to replace natural sand. The study evaluates both fresh and hardened properties of concrete, including workability, compressive strength, water absorption, and durability. Results indicate that the inclusion of stone dust improves workability and enhances strength up to an optimum replacement level. Beyond that, performance may decline. The study also highlights environmental and economic benefits, as the use of stone dust reduces waste and lowers construction costs.
