=+41. Ultra high performance concrete (UHPC) is a relatively new construction material that offers strong adhesive properties with other materials.The authors of “Adhesive Power of Ultra High Performance Concrete from a Thermodynamic Point of View” (J. of Materials in Civil Engr., 2012: 1050–

1058) investigated the intermolecular forces for UHPC connected to various substrates. As reported in the article, here are the work of adhesion measurements (in mJ/m2

) for five samples of UHPC adhered to steel:
