Rheological study of interactions between MHEC and superplasticizers in aqueous solutions for applications in cement industry [PDF]
, 2011 Innovative cement-based materials are characterized today by rather complex formulations. In particular, when cement pastes are considered, their formulation generally includes two different types of polymers: a rheology modifier (RM) (typically a ...

Influence of selective acid etching on microtensile bond strength of a self-adhesive resin cement to enamel and dentin [PDF]
evaluate the selective acid etching of enamel and dentin on microtensile bond strength (¦ÌTBS) of a self-adhesive resin cement. Methods: Forty-eight bovine teeth were selected and had the buccal surface ground to obtain a flat dentin (n=24) or enamel (n ...
