采用水泥基材料孔结构和界面过渡区逐渐优化的方法,设计了普通混凝土(Ordinary Concrete,简称OC)、高性能混凝土(High Performance Concrete,简称HPC)、低渗透混凝土(Low Permeability Concrete,简称LPC)、普通砂浆(Ordinary Mortar,简称OM)、无细观界面过渡区水泥基复合材料(Meso-interfacial transition zone-free cement-based materials,简称MIF)等5种水泥基材料,其抗离子渗透性能排列顺序为:LPC>HPC>OC,OM>OC,MIF>OM,MIF>LPC,其孔隙率、最可几孔径、孔径≥50nm的孔含量的排列顺序均为:LPC

By means of gradual optimization of pore structure and interfacial transition zone,five kinds of cement-based materials were designed,including ordinary concrete (OC),high performance concrete (HPC),low permeability concrete (LPC),ordinary mortar (OM) and meso-interfacial transition zone-free cemenvbased materials(MIF).As for the ability to resist chloride ion penetration,the order is LPC>HPC>OC,OM>OC,MIF>OM,MlF>LPC.As for porosity,the most probable pore radius,and the content of the pores with radius of larger than 50nm,the order is LPC
