Abstract

The aim of this project was the development of the scientific basis for methodologies that enable the production of renewable sustainable cement (i.e. BioCement) based on ashes derived from the conversion of biomass residues. Within this project, biomass ash and derived products were developed at the laboratory scale, and their functionality was tested with respect to sustainability and composition (relative to OPC). The ultimate goal was to prove the possibility of replacing traditional Portland cement with a renewable BioCement in typical cement-based products such as concrete. The environmental superiority of theoretical BioCement is based on assumed negligible CO2 emissions during production. Through a Life Cycle Analyses on the developed biomass ashes (and preferably fully functional BioCement), the environmental impact and the potential to replace Portland cement with theoretical BioCement was quantified. The investigations included three types of biomass (ash) utilization:
