The Roles of B₂O₃ and P₂O₅ in the Formation of Cement Clinker

Abstract:

The roles of B₂O₃ and P₂O₅ in the formation of clinker which stand on the each side of the IV main group are discussed. The results show that the role of B₂O₃ and P₂O₅ in the formation of clinker are different: B₂O₃ has evident effect, which is lost at higher temperature, on the consumption of CaO at 1300°C while the effect of P₂O₅ is mainly reflected at higher temperature, especially at 1400°C; Suitable B₂O₃ makes C₃S transform form R to M₃, but P₂O₅ induces C₃S change into M₁. What they have in common is that more B₂O₃ and P₂O₅ will decrease the content of C₃S.
