Interaction of cement model systems with superplasticizers investigated by atomic force microscopy, zeta potential, and adsorption measurements

Microstructural changes of globules in calcium–silicate–hydrate gels with and without additives determined by small-angle neutron and X-ray scattering

“…Uchikawa et al [20] conducted atomic force microscope (AFM) measurements on Ordinary Portland Cement with and without PCE and found that the addition of PCE significantly increases the intensity and range of the steric repulsive force introduced by the additives. Ferrari et al [21] investigated the interaction of PCE23-6 with model surfaces using AFM, adsorption isotherms, and zeta potential. The main tendency for PCEs in cement is to adsorb on positively charged surface in order to avoid positive-negative particle aggregation.…”

First-principles Study of Electronic and Magnetic Properties of Manganese Decorated Graphene

“…[e.g., Wolf et al, 2013]. The interaction of graphene with foreign particles can be understood in two types of adsorptions: chemisorption (due to local electronic rearrangement) and physisorption (due to non-local electronic interactions, named van der Waals forces) [e.g., Ferrari et al, 2010]. The nature and strength of interaction between the adatom and graphene is determined by the electronic/magnetic properties of the interacting particles [e.g., .…”

Fuerzas de repulsión de aditivos superplastificantes en sistemas de escoria granulada de horno alto en medios alcalinos, desde medidas de AFM a propiedades reológicas

“…El grosor de la capa de aditivo superplastificante adsorbido sobre las muestras α-Al 2 O 3 y escoria a pH=11,7 y 13,6 se determinó mediante la técnica de Microscopía de Fuerzas Atómicas (21)(22)(23)(24)(25).…”

“…The thickness of adsorbed layers of superplasticizers was determined for α-Al 2 O 3 samples and slag samples at pH=11.7 and 13.6 using the colloidal probe AFM technique (21)(22)(23)(24)(25).…”
