Mineral Composition and Performance of Phosphoaluminate Clinker with Addition of SO₃

Abstract:

The effect of SO₃ on the mineral composition and performance of phosphoaluminate clinker was investigated by means of XRD, IR and SEM. Also, the compressive strength of clinker was performed. The experimental results showed that a certain amount of SO₃ would promote the formation of calcium phosphoaluminate mineral, which was good for the strength development of phosphoaluminate clinker. Moreover, the addition of SO₃ was benefit to the formation of C₄A₃ in phosphoaluminate clinker. So, the 5% dosage clinker owns a good strength development.
