Paper Title:
Effect of Aggregate Pre-Wetting and Air-Entraining Agent on Durability of Lightweight Aggregate Concrete
  Abstract

Rapid carbonation test and gas permeability radio method are used to study the durability of lightweight aggregate concrete. The concrete includes foam,lightweight aggregate,pre-wetting and air entraining. The test results show that The combined-effect of air entraining agent(AEA)and aggregate pre-wetting can increase permeability. The anti-carbonation capacity of pre-wetting and air entraining lightweight aggregate concrete is 40% greater than that of ordinary concrete.gas permeability radio of pre-wetting and air entraining lightweight aggregate concrete is half of that foam concrete and expanded pearlite concrete.
