Crushed Waste Glass (CWG) Re-use as a Synthetic Aggregate in Shotcrete Production

Dr. Mehdi Serati

The global demand for underground constructions is expected to boom in the coming years with 9 out of 12 current state and federal government infrastructures related to underground road and rail tunnelling projects in Australia already. With such an increased demand for tunnelling, shotcrete (also known as sprayed concrete) has also received increasing attention for ground support in tunnels and mines. Shotcrete is concrete in nature but could be much richer in sand to avoid rebound. But, the world is running out of sand very rapidly on a global scale. Recycling glass wastes to replace sand is therefore becoming of urgent interest in Australia and worldwide. This presentation reviews the claims of an imminent global sand scarcity and presents the results of a recent study on the applicability assessment of waste glass as a synthetic aggerate in geotechnical engineering and shotcrete production.
