Aimed at high strength, durability requirements of airport pavement concrete, by adding Na2SiO3 and NaOH complex activator in slag, self-compacting alkali-activated concrete (AAC) is prepared with slump 160 mm and upwards, flexural strength 7 d and 28 d respectively reaching 7.6 MPa and 8.5 MPa. Its durability, distortion, construction and economy performances are also studied by comparing with porland concrete. The results show that the anti-permeability, anti-frozen, corrosion resistance and abrasion resistance of SCAAC are superior to the porland concrete, and its anti-permeability rank exceeds S40, anti-frozen rank exceeds F300, sulfate resistance and abrasion are excellent. The Alkali-activated concrete is of low deformation concrete but with ratherish great early deformation, therefore early keep should be reinforced. AAC can meet the requirements of airport pavement in workability, strength, durability, constructing and economy,and it can be applied to the construction of airport pavement.
