Recycling mine waste to improve the acid resistance of cement-based composites for underground structures
DownloadFall 2020
Cement-based composites are widely used in underground structures for various applications, such as tunnel lining, mine backfilling, and grouting. However, cement-based composites are highly susceptible to attack by sulfuric acid that can be naturally generated around underground structures...

Synthesis of workable, strong and acid-resistant N-A-S-H geopolymers incorporating dry-water
DownloadSpring 2023
The production of cement-based materials releases numerous greenhouse gases into the atmosphere and therefore, accelerates global warming. The search for an alternative to Portland cement systems has thrown up the family of alkali-activated geopolymers as a potential choice. In civil engineering,...
