摘　　要：本文测试了山西省不同地区典型的粉煤灰、矿渣粉两类矿物掺合料矿物组成、基本物理力学性能，试验研究了不同掺量的矿物掺合料对净浆流动度和力学性能的影响。根据其特性，提出了山西地区复掺粉煤灰、矿渣粉矿物掺合料在混凝土中应用的技术条件，并将粉煤灰、矿渣粉双掺混凝土在高速公路工程中成功应用。In this paper, the mineral composition, basic physical and mechanical properties of several typical mineral admixtures of fly ash and blast furnace slag in different areas of Shanxi province were tested. The influence of different replacement with mineral admixtures on fluidity of cement paste and mechanical properties was studied. On the basis of their characteristics, application technical standards of fly ash and slag powder mineral admixtures with double addition in concrete in Shanxi province was proposed. Concrete incorporated with fly ash and blast furnace slag was applied to expressway project successfully.
