Cement paste–epoxy adhesive interactions
Construction and Building Materials, 2011In the field of civil engineering, the durability of concrete assemblies using adhesives is widely conditioned by the properties of the interface between the resin and the mineral support (concrete). In this context we studied first the molecular interactions at the interface between an epoxy resin and cement pastes by several approaches based on XPS ...

Influence of silane on hydration characteristics and mechanical properties of cement paste
, 2020In the present study, silane coupling agents (SCAs) were used as admixture in cement paste. The influence on the cement hydration in different stages as well as the mechanical properties were well investigated.

Controlling the Cohesion of Cement Paste
Langmuir, 2005The main source of cohesion in cement paste is the nanoparticles of calcium silicate hydrate (C-S-H), which are formed upon the dissolution of the original tricalcium silicate (C(3)S). The interaction between highly charged C-S-H particles in the presence of divalent calcium counterions is strongly attractive because of ion-ion correlations and a ...
