景洪水电站混凝土掺和料选择试验研究

The Test and Research on Concrete Additives to Be selected for the Construction of the Jinghong Hydropower Project

景洪水电站坝址周边地区粉煤灰资源非常匮乏,因此对当地的水淬矿渣、凝灰岩粉、石灰岩粉等材料进行试验研究。通过试验、分析,为景洪工程混凝土提供技术性能理想、经济可行的掺和料及配比,其中石灰岩粉作为混凝土掺和料在国内尚属首次。

Because of shortage of fly ash in the vicinity of the Jinghong dam site area test and research were made on the water-granulated slag, tuff powder and limestone power which are available locally. The test and research results have proved that they are technically ideal and economically practicable for use in concrete as additives. It is worthy to be pointed out that limestone is used as an additive in concrete for the first time in the country. The paper has also put forward their mix proportion.
