Development of low temperature lightweight geopolymer aggregate, from industrial Waste, in comparison with high temperature processed aggregates

The purpose of this study is the development of new aggregates based on geopolymer formulations in order to replace commercial lightweight aggregates (LWAs), which require high energy consumption due to its industrial sintering process. Geopolymers are innovative materials which are synthesized at low temperature and which exhibit efficient mechanical and thermal properties. Thus, the feasibility of producing geopolymer aggregates was...
