the abrasive wear resistance, allowing the establishment of a hierarchy in view of selecting materials for specific applications.
Materials and procedures Ductile iron with the chemical composition indicated in table 1 was used in these experiments as the base metal and a WC powder with 6 micrometer of average diameter was used as the main material to be inserted.
The tests on inserted materials show that the respective weight loss rate is the same (2.0x10 -4 g per revolution), whatever the quality of the surface finish imposed to the test piece, lower than the one obtained for the non inserted material (3.0x10 -4 g per revolution).

Introduction Based on the successfully-designed cement-base composite formwork, our research group has developed a new type of insulated composite formwork made of cement-base formwork and insulation materials [1,2].
Next, polyurethane (PUR), which was served as the insulation materials, was cut into required dimensions, and slotted on one side in order to enhance the bonding with concrete.
