Projct Athr ams to dvlop a nw, nnovatv class o clnkrs wth a lowr nvronmntal ootprnt.Clnkr s th man componnt usd to produc cmnt, through grndng and mxng t wth addtons lksulphats, and cmnttous matrals such as fy ash, slag or othr pozzolanc matrals. Lss lmston srqurd to produc Athr cmnts, whch ar also manuacturd at lowr tmpraturs and usng lssnrgy than convntonal Portland cmnt.
Ths allows a 25-30% reduction in CO2emissions durng th producton procss.
Athr clnkrs can b mad rom convntonal raw matrals that ar sutabl or us n largscal cmnt manuactur: lmston, clay, ron and bauxt. Thy can also b producd nxstng ndustral nstallatons - rotary klns - atr crtan procss adaptatons hav bn mad.Athr cmnts ar xpctd to or smlar prormancs to convntonal Portland cmnt

key stages In the project
The three-year project consists of:
Two ndustral trals at Laarg cmnt plants n europ to produc Athr clnkrs.
