摘要：

The influence of CuO on the formation and coexistence of 3CaO center dot SiO2 and 3CaO center dot 3Al(2)O(3)center dot CaSO4 minerals in Portland cement containing 3CaO center dot 3Al(2)O(3)center dot CaSO4 mineral is reported in this paper. The results show that a suitable amount of CuO can lower the clinkering temperature and improve the burn-ability of clinkers. It can also promote the formation of 3CaO center dot SiO2 and 3CaO center dot 3Al(2)O(3)center dot CaSO4 minerals and facilitate the coexistence of the two minerals in the clinkers. But adding 1% CuO to the raw material can cause the decomposition of 3CaO center dot 3Al(2)O(3)center dot CaSO4. C) 2006 Elsevier Ltd. All rights reserved.
