摘要：In this paper, the tensile bond performance of different bonding mortars for lightweight composite boards of autoclaved aerated concrete which can be prefabricated in factory is studied. The performance requirements of bonding mortar for the composite boards are proposed. The research methods refer to relevant Chinese standards. The results indicate that the tensile bond strength of bonding mortars for the lightweight aerated concrete substrates varies with the curing age increasing. The special bonding mortar for prefabricated composite board of light weight aerated concrete should have the characteristic of early and relatively high strength in a short curing age. And its early tensile bond strength should not be less than 0.35MPa in 3 hours.
