This paper presents a laboratory study on the effect of air entraining agent on the performance of thermal insulating mortar with glazed hollow bead. The test results show that with the dosage of air entraining agent increases, the consistency of thermal insulating mortar increases, apparent density, thermal conductivity and drying shrinkage decline, However, the compressive strength greater losses owing to excessive consumption of air entraining agent; air entraining agent within a certain dosage can significantly improve the operating performance of thermal insulation mortar, increase its consistency and reduce its apparent density, thermal conductivity coefficient and drying shrinkage. Due to excessive addition of air entraining agent, the apparent density, thermal conductivity and compressive strength of thermal insulation mortar all increase. For a specific insulation mortar, there will exist the best mixing amount of air entraining agent.
