Abstract

This study was conducted to address the problem of natural sand scarcity by utilizing crushed stone, a by-product of the stone crushing process, as a fine aggregate for concrete. The primary objective was to determine the mix proportions for B15 concrete using crushed stone in Nghi Loc commune, Nghe An province, and to evaluate the key physical and mechanical properties of this type of concrete. Laboratory tests were conducted to determine the physical and mechanical properties, such as particle size distribution, slump, volumetric weight, steel-concrete adhesion, and compressive strength at different ages of concrete mixtures. The initial results showed that the compressive strength of B15 concrete, as measured in cubic concrete samples using crushed stone, was 7.6-12.9% higher than that of concrete using river sand. Additionally, the adhesion strength of steel reinforcement to concrete using crushed stone was approximately 8.2% higher. The application of crushed stone not only brings economic benefits but also has environmental significance. This study provides a crucial scientific basis for recommending the widespread use of local crushed stone in the construction industry, particularly for projects in Nghe An.
