根据岩滩工程７～１０年龄期的少水泥高掺粉煤灰碾压混凝土芯样的微观、亚微观及部分宏观性能试验结果，对该混凝土的长龄期性能进行讨论。该混凝土水化产物正常、稳定、结构致密。随着龄期的进一步延长，粉煤灰还会不断水化，混凝土的孔隙结构不断改善，强度仍在增长，其它性能将得到进一步提高。水化产物稳定，混凝土抗溶蚀能力强。
According to the microscopic, submicroscopic and partial macroscopic performance test results of the low cement high fly ash RCC core sample from 7 to 10 years of Yantan Project, the long-term performance of the concrete is discussed. The concrete hydration products are normal, stable, and dense in structure. With the further extension of the age, fly ash will continue to hydrate, the pore structure of concrete will continue to improve, and the strength will continue to increase. Other properties will be further improved. The hydration products are stable and the concrete has a strong resistance to dissolution.
