Research on Mechanism of Phosphoaluminate Cement Enhanced the Mechanical Performances of Portland Cement

The article prepared the composite cement which is composed of phosphoaluminate-portland clinkers, gypsum and additive. The optimal ratio of the composite cement have been decided by the method devised. Mechanical performances of the composite cement have been tested and the techniques of X-ray diffraction, scanning electron microscope, infrared analysis have been employed to analyze the hydration products. It has been discussed that the mechanism of Phosphoaluminate cement enhanced the mechanical performances of Portland cement.
