摘要：
The changes of compressive strength and elastic modulus of concrete specimens with water-to-water ratio of 0.25, different content of fly ash (0%,20%,40%) and different ages (7d, 14d, 28d, 56d, 90d, and 120d) were studied. The results show that the amount of fly ash has a great influence on the compressive strength and the elastic modulus of the high-strength concrete.The compressive strength and elastic modulus of concrete with 0%, 20%and 40%content increase with age, but the compressive strength and elastic modulus decrease with the same age.
