[1212] FRESH AND HARDENED PROPERTIES OF ALKALI-ACTIVATED CONCRETE INCORPORATING BLAST FURNACE SLAG AND CASTING SAND DUST
Keywords:alkali-activated concrete、casting sand dust utilization、waste material recycling、compressive strength analysis、concrete workability
This study examines the inclusion of casting sand dust in alkali-activated concrete. Challenges with workability and strength were improved by replacing Fly Ash with Blast Furnace Slag in the mix. Improved results were observed with a 30% replacement of casting sand dust in concrete, showing a strength of 35 MPa, and with a 40% replacement in mortar, which exhibited a strength of 43 MPa after seven days. This research underscores the practicality of casting sand dust in concrete mixtures, aiding in the use of industrial by-products.
