Physical and Mechanical Properties and Hydration of High Belite Sulphoaluminate Cement Modified White Cement

Abstract

Abstract: White Portland cement (white cement) has good whiteness and it is a cementing material with decorative effects. Aiming at the problems of long setting time, slow early strength development and large shrinkage deformation of this kind of cement, the high belite sulphoaluminate cement was used to modify the white cement. The effect of high belite sulphoaluminate cement mixed with 10% to 30% (mass fraction) on the setting time, mortar strength and free expansion rate of white cement was systematically studied. Hydration microcalorimeter, XRD, TGA, SEM, and other methods were used to analyze the hydration process, hydration products and microscopic morphology of the composite cementitious system. The results show that high belite sulphoaluminate cement increases the hydration heat release rate of white cement, and significantly shortens the setting time of white cement. The modified white cement hydration product generates a large amount of AFt, which grows interspersedly in the C-S-H gel, consuming part of the Ca(OH)₂, making the structure more compact, strength higher, and expansion performance better.

Key words: white Portland cement, high belite sulphoaluminate cement, modification, composite cementitious system, hydration process
