Leeds University Selects Leca® Lightweight Expanded Clay for Engineering Research



University of Leeds research into Leca Lightweight Expanded Clay Balls Aggregate

Leca® Lightweight Expanded Clay Aggregate has been selected by the School of Civil Engineering at The University of Leeds for research in producing a new eco-friendly steel-concrete composite (SCC) flooring system characterised by its reduced weight, energy consumption, and CO2.

Dr Konstantinos Daniel Tsavdaridis (Associate Professor of Structural Engineering): Our aim is to produce a new eco-friendly steel-concrete composite (SCC) flooring system characterised by its reduced weight, energy consumption, and CO2 emissions when compared with the currently used SCC flooring systems. For further weight reduction in addition to the reduction due to the novel configuration of the system, Leca® LWA has been chosen to replace normal aggregates following an extensive Life Cycle Assessment (LCA) analysis. About 46% weight reduction has been achieved along with 2.1% reduction in embodied energy and 9.8% reduction in embodied carbon when compared with normal concrete. An experimental campaign is now undergoing in the School of Civil Engineering at the University of Leeds to validate the load carrying capacity and performance of this new prefabricated flooring system.”
