摘要：

Five fly ash concretes were found to gain considerable strength beyond 28 days when standard cured in water at 20°C. However, strength development came to an almost complete stop after 3 1 2 years, at what time the fly ash activity factors with respect to concrete compressive strength ranged from 0.86 to 0.93. © 1990.
