Influence of Expansive Additives on Hydration of C_3A;

Research on hydration of magnesium oxide from roasting hydrated magnesium chloride;

Influence of additives on performance and hydration process of cement;

The experiments show that a few calcium chloride will result in the increase of the fluidity loss of portland cement paste,Calcium chloride can decreaae the dissolution rate of dihydrate gypsum in calcium hydroxide saturated solution and increase its dissolubility.

The physical constitution and hydrate of this cement with high volume fly-ash and slag wastage is detected by scanning electron microscope(SEM), X-ray diffraction(XRD) and differential thermal analysis(DTA) etc.

By using scanning electron microscope(SEM) the hydrate of highly free calcium oxide(f CaO)cements is studied,and the distribution and crystalline characteristics of calcium hydroxide in cement are investigated and the different boundary characteristics between calcium hydroxide with CSH at early hydration stage and later stage as well.
