三峡工程在工程建设期间首次采用粉煤灰用于主体工程施工,为水电建设的大中型水电工程使用粉煤灰变废为宝起了带头作用。本文测算了三峡工程的粉煤灰掺用量,粉煤灰在混凝土配合比中所产生的经济价值;测算了粉煤灰代替水泥,使三峡工程少用水泥所起到的在建设期间的节能减排效果。 During the project construction, the Three Gorges Project adopted fly ash for the first time for the construction of the main project, playing a leading role in using large and medium-sized hydropower projects with fly ash to turn waste into treasure. This paper estimates the amount of fly ash blended in the Three Gorges Project and the economic value of fly ash in the concrete mix. It estimates that the fly ash instead of cement reduces the energy consumption during construction of the Three Gorges Project with less cement Row effect.
