在水利电力建设工程中,推广应用粉煤灰作大坝混凝土的掺合料,好处很多,势在必行。在施工工艺方面,以往我国在现场掺粉煤灰的施工方法,以干法居多。自从闽江工程局在福建省池潭水电站大坝混凝土工程中应用湿法掺粉煤灰工艺后,我省奉化县亭下水库大坝混凝土工程中也应用了湿法掺粉 In water conservancy and electric power construction projects, the use of fly ash as an admixture for dam concrete has many advantages and is imperative. In the aspect of construction technology, in the past, the construction method of fly ash in China was mostly dry method. Since the Yongjiang Engineering Bureau applied the wet method with fly ash in the dam concrete project of the Chitan Hydropower Station in Fujian Province, the wet concrete method was also applied to the dam concrete project of the Tingxia Reservoir of Fenghua County in our province.
