Abstract :	[en] The definition of the adhesion itself presents a duality : on the one hand, adhesion is understood to be a process through which two bodies are brought together and attached (bonded) to each other, in such a manner that external force or thermal motion is required to break the bond. The term "adhesion" (or "sticking") is usually applied in this sense in colloid research on coagulation phenomena. On the other hand, we may examine the process of breaking a bond between bodies that are already in contact; and here, as a quantitative measure of the intensity of adhesion, we can take the force or energy required to separate the two bodies. We studied this problem in the context of repairing mortars laid down on a concrete support; we focused our research on the behaviour of a cementitious slurry applied on two types of concrete support, characterised by their surface preparation (sandblasted and polished surface). We measured and observed the penetration of this slurry into the concrete support.
