Paper Title:
Durability of Green High Performance Alkali-Activated Slag Pavement Concrete
  Abstract

Green high performance alkali-activated slag pavement concrete(ASC) was prepared by adding Na2SiO3 and NaOH complex activator in slag. Physical, mechanical performance and durability of ASC were studied by workability, strength, hydrostatics and chlorin ion penetrability, fast freeze-thaw cycle tests and abrasion resistance tests. The results show that slump of ASC exceeds 160mm, fluidity and workability is excellent. 28d compressive and flexural trength of AAC are 91.9MPa and 8.5MPa, 7d compressive and flexural strength are 84.8MPa and 7.6MPa, which belongs to high–early strenth concrete. And its impermeability rank exceeds S40, chlorin ion impermeability is excellent, 6h eletricity is 1751~1894 coulomb, and its anti-frozen rank exceeds F300, which can meet the anti-frozen requirements in frore area. Depth of abrade slot is 0.45~0.96mm, abrasion resistance of ASC is 4.99, so its physical, mechanical performance and durability are superior to traditional portland concrete.
