A kind of cement-based foam insulation material is made of cement and fly ash as main raw materials, and the composite excitation agent and foaming agent by the physical foaming. The influence of dry mixing and wet mixing on the performance of lightweight insulation material is researched. Their influence mechanism is also discussed. Experiments show that by using the dry mixing, the foam insulation materials have 1.22 MPa bending strength, 2.95 MPa compressive strength and 0.072 W/m·K thermal conductivity when mixing 1.2%of fiber.
