Abstract: Cement, fly ash, foaming agent, foam stabilizer, polypropylene fiber and water-proofing agent are used as raw materials to manufacture cement-fly ash foaming thermal insulation material. The effects of chemical foaming agent on volume density, thermal conductivity and strength of foaming thermal insulation material are studied. The influences of foam stabilizer on foam structure, thermal conductivity and strength are discussed, and the effects of the polypropylene fiber on flexural strength, the waterproof agent on water-proofing performance are also studied. The technique parameter of cement-fly ash foaming thermal insulation material is gotten by experiment. Cement-fly ash foaming thermal insulation material is characterized by fireproofing, lightweight, thermal insulation and freezing resistance, these above properties are all accordance with the rules of relative national standards.
