[1212] 高炉スラグ微粉末および鋳物砂ダストを用いたアルカリ活性コンクリートのフレッシュおよび硬化特性
キーワード: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.
