Blended Portland cements have so far been produced with an admixture of slag, fly ash and other ingredients. The present
paper surveys the results of the investigation into the properties of a new type of blended Portland cement containing waste
steel foundry dust as admixture. The optimum way of preparation of this type of cement consists in the simultaneous milling
of clinker, gypsum and waste steel foundry dust. The addition of the last component exerts an influence on the hydration of
the blended cement. |
