摘要：

Paste hydration of B2O3-stabilized α′- and β-C2S was studied at reaction times between 5 hours and 28 days. Data on the degree of hydration determined by X-ray diffraction at different ages were used to evaluate hydration rate constants. The higher rate of α′-C2S hydration resulted in the higher compressive strengths of the α′-C2S-alite paste as compared with the β-C2S-alite paste. Differences in crystal imperfections of the two C2S-polymorphs were determined using electron microscopy and electron diffraction. © 1978.
