Study of bond force on polyurethane foam materal and fly ash concrete

Through factors of the various thickness and high degree of the Polyurethane Foam to research and analyse the bond force between the Polyurethane Foam material and fly ash concrete.The result shows: the bond force between the Polyurethane Foam and fly ash concrete has relevant to the thickness of the Polyurethane Foam and almost irrelevant to its height,Measuring 40 mm diameter Polyurethane Foam bond force is 60 kPa,50 mm diameter is 100 kPa.
