dcterms:description
The paper is aimed at the assessment of the influence of P2O5 combined with other minor oxides (SO3, MgO, K2O a Na2O) on the formation and phase composition of Portland cement clinker. It was determined, that some oxides and their combinations partially eliminate the negative influence of P2O5 on the phase composition of clinker and expecially on the formation of alite. It is stated, that the combination of P2O5 with certain minor oxides leads to cements with better technological properties than cements prepared from clinkers doped only with P2O5. The positive influence lies especially in acceleration of hydration and increase of early strengths, caused by higher content of alite, increased sulfate modulus and higher content of soluble alkalis. Paper at the conference Ecology and new building materials and products, ISBN 978-80-254-4447-4.
