- Abstract
Magnesium sulphoaluminate (MSA) cement is a new type of inorganic coating for steel substrate with excellent fire retardant performance. In order to make full use of the advantages of MSA cement based coatings, the effect of fly ash on setting time, strength of MSA cement paste coating was studied. The phase compositions of MSA cement hydration products were analyzed by X - ray diffraction (XRD) and scanning electron microscopy (SEM). The results showed that the addition of fly ash prolongs setting time and increases the strength of MSA cement at 1 day (d) significantly. After adding fly ash, no new hydration products were generated, but it can significantly improve morphology of MSA cement with the compact structure of hydration products.
