摘　　要：作为抗渗性的表征国内外有三种,即透水性、透气性和抗氯离子渗透性。通过试验,从透水性和抗氯离子渗透性两个方面研究了机场道面混凝土掺入引气减水剂和粉煤灰后与普通混凝土的比较,表明两者都能提高混凝土的抗渗性,进而提高其耐久性,并与配合比密切相关。There are three characterizations of permeability resistance at home and abroad,i.e.water permeability,gas permeability and chloride ion penetration resistance.Through test,the airport pavement concrete mixed with air-entraining water reducing agent and flyash is compared with common concrete from water permeability and chloride ion penetration resistance.It is indicated that both concrete can improve permeability resistance and thus improve concrete durability,but the former is closely related to mixing proportion.

关 键 词：引气减水剂 粉煤灰 抗渗性 透水性 抗氯离子渗透性 耐久性
