The HE EXCEED project aims to valorise the mining waste streams (quartz, feldspar, mica) generated at several stages of the beneficiation of (LCT) pegmatite and (RMG) ores as secondary raw materials in construction applications. These include alkali-activated materials (AAMs), supplementary cementitious materials (SCMs), ceramics and lightweight aggregates (LWA) for concrete. The project ensures safety and environmental feasibility in line with standardisation practices.

Turning Waste Streams into Valuable Materials

What if quartz, feldspar and mica waste streams from lithium ore beneficiation could become valuable construction materials?

This online webinar will present selected results from the project, with a particular focus on the properties and potential applications of the developed materials, applicable standards and testing methods, and challenges related to the use of secondary raw materials in construction materials.

Key webinar topics

• Mining waste streams for use in construction materials
• Innovative construction applications: ceramics, sustainable binders (AAMs and SCMs) and lightweight aggregates
• Material performance and environmental safety
• Standardisation and regulatory requirements
