摘　　要：高炉矿渣微粉作为一种常用的辅助胶凝材料,由于其较强的潜在胶凝活性被广泛应用于水泥混凝土中。因此,矿渣微粉的火山灰活性发挥对水泥混凝土材料的力学性能与耐久性尤其重要。文中以马钢矿渣微粉为例对其火山灰活性进行了综合评价,并根据国内外研究进展归纳总结了影响其火山灰活性的关键因素,为矿渣微粉的改性与在水泥混凝土中应用提供参考。As an excellent pozzolanic activity supplementary cementitious materials,ground granulated blast slag(GGBS)is widely used in cement concrete industry.Because the pozzolanic activity of GGBS is closely related to the mechanical and durability properties of concrete.Therefore,in this paper,the pozzolanic activity of GGBS and its impact factors were characterized in detail by using the products of Ma Gang Company.Furthermore,the pozzolanic activity effect factors of GGBS were also discussed according to the experiment data and literature reports,which can be as a reference for the GGBS modification and application in concrete industry.
