摘要
澜沧江中游河段上的大朝山电站是以发电为主，兼有防洪、灌溉、旅游等综合利用的水利枢纽工程。DCSIC4标承担进水口坝段施工，混凝土设计方量为25万m3。在大体积水工混凝土中掺用磷矿碴(P)和凝灰岩(T)粉等量取代水泥在国内尚属首次。PT混凝土不仅可以达到预期的混凝土性能，且能减低成本，具有广阔的应用前景。
The Dachaoshan hydroelectric project, on the middle reach of the Lancangjiang river, will mainly produce electricity and also will provide flood control, irrigation and tourism benefits. The Contract No. DCS/C4 includes the construction of power intakes with a concrete volume of 250 000 m3. It is the first in China that the concrete added with PT powder equal to cement in dosage is applied to the hydraulic structures. The PT concrete not only can achieve the desired concrete properties, but reduce the c...
