On a software development that aspires to make residue valorisation easier The story of the exploded excel file A. Peys, M. Orfanakis, Y. Pontikes

History of intentions 1. Automatisation of own calculations 2. Calculations in research group – Excel tool 3. Automated calculations in research group – Software 4. Calculations/database for anyone interested – Online available software People to be reached with software time 2

The aspiration Ease research/development… …for people that believe that global warming is real… …and see huuuge oportunities in the valorisation of residues. Trust me, their the biggest opportunities you’ve ever seen! rightsidenews.com viktormacha.com 3

More concrete*: The goal *well, ideally we make less concrete more concrete More concrete*: The goal Centralise knowledge on the behaviour of residues as reactive precursors in building materials Database of residues – treatments – database of products (cements, concretes...) Support calculations Tools for calculating phase composition in kiln Tools for synthesis of activating solution alkali activation Financial – environmental assessments 4

The goal Centralise knowledge on the behaviour of residues as reactive precursors in building materials Database of residues – treatments – database of products Residues/treatments from KU Leuven projects Accredited partners 5

Database of residues Collect a database of Chemical compositions Industry of origin X-ray diffraction patterns/FTIR spectra/... Reactivity Example from mineralogy: RRUFF database rruff.info 7

Database of residues Example from mineralogy: RRUFF database 8 rruff.info 8

What treatments are included? Slide from: Y. Pontikes, “Fe-Ca-silicate slags: when purpose driven research challenges perception of what is feasible” Inaugural lecture 03/2017. What treatments are included? Reproduce slide Yiannis 11

The goal Centralise knowledge on the behaviour of residues as reactive precursors in building materials Database of residues + treatments = database of products Residues/treatments from KU Leuven projects Accredited partners 12

Database of products Residue + treatment = product (cements, concretes...) Properties (compressive strength, setting kinetics) XRD/FTIR/... spectra Get inspiration from others: Materials Genome Initiative US (Obama) initiative Collecting data on new materials (they also provide funding) 13

Database of products Interaction with community: Anyone can construct his/her own database Help in analysis of data Use of support tools Collection of 1 common “accredited” database Added after check of methodology (and approval of user) Delivering X datapoints = free use of this database Commercial idea = pay for accredited database if not contributing to it 14
