The setting time results indicate that when the cement composition consists of only 30 % G oil well cement and a large proportion of fly ash(65 %∼70 %), the setting time is prolonged, especially at low curing temperature (3°C,10°C). On the other hand, with a high proportion of fly ash, the early compressive strength is quite low.
