Sustainable shotcrete production with waste glass aggregates

Abstract

Article highlights This study investigates sand replacement with glass aggregates in shotcrete production for use in excavation industry. Tested shotcrete mixes containing glass aggregates exhibited a similar or higher strength properties at both early and late ages. Results suggest that waste glass reuse as synthetic aggregates can reduce water and cement consumption to generate a low-cost and eco-friendly shotcrete.
