Blast furnace slag binder properties activation by lime production waste
Blast furnace slag under study has manifested unequivocal binding properties. They were activatedby grinding and by adding of lime production waste and compared with ungrounded fraction 3mm. The activation efficiency of grinded slag was observed only during the first 90 days and ofungrounded slag –...

| description |
Blast furnace slag under study has manifested unequivocal binding properties. They were activatedby grinding and by adding of lime production waste and compared with ungrounded fraction 3mm. The activation efficiency of grinded slag was observed only during the first 90 days and ofungrounded slag – during 2 years. Uniaxial resistance strength of the materials on the 90th daysvaried from 0.83 till 5.07 MPa, during one year it increased till 7.46 – 16.00 MPa and during 6years – till 12.48 – 20.40 MPa. The strengthening of the slag is ascribed to the appearance of newamorphous formations, which transform into a stone-like condition over time. The only new crystalformations, detected over a 6-year-long hardening process, were various crystalline carbonates insuch small amounts that they cannot be responsible for the materials’ highly significant strength.Their long-term properties allow these types of slag to be used as concrete-like or binderconstruction materials. |
