RISUpcycling Spent Waterglass Foundry Sand into Reactive Fine Aggregates for Alkali-Activated Slag to Achieve Enhanced Compressive Strength
Publisher: American Society of Civil Engineers
Abstract: Spent waterglass foundry sand (SWFS) is a major waste in foundry industries and should be disposed of preferentially. Two SWFS subjected to working temperatures of 100°C (SWFS1) and 800°C (SWFS8) were prepared to investigate ...
Producing Carbon-Negative Bricks by Regenerating C-S-H from Carbonated Recycled Concrete Fines
Publisher: American Society of Civil Engineers
Abstract: This study proposes the production of bricks utilizing underutilized fine powders, predominantly consisting of old cement paste derived from the recycling of demolished and waste concrete. Four brick designs were developed ...
