摘要
The influence of lime and/or gypsum on the C4AF hydration was examined and the results were compared with those obtained for the C3A hydration. Gypsum is more effective than CH in retarding the hydration of C4AF. Ettringite produced in the C4AF hydration in the presence of CS·H2 seems to be more stable than that produced in the C3ACS·H2H2 system. The consumption of gypsum, the transformation of ettringite into monosulfate and the hydration of C4AF in the C4AFCS·H2H2O system are much slower than those in the C3ACS·H2H2O system. The retardation of hydration of C4AF or C3A in the presence of CS·H2 is further increased by the addition of CH. © 1979.
