The mechanical and other properties of ionomer cements
Ionomer cements, a novel composite material, are formed at ambient temperatures by mixing an aqueous polyacid with an ion-leachable powder. The glass ionomer cement known as ASPA, a dental restorative material, produces strong and hydrolytically stable cements. Applications of this material outside …

Interactions Between Portland Cements and Carboxylated and Naphthalene-Based Superplasticizers
In the final part of this study, the relation between the concrete slumps and the paste rheology is established. However, concretes required much less superplasticizer than paste to be dispersed. The differences in the shear history between the concretes and the pastes possibly explain such …

Calcite cements in carbonates of the Sverdrup Basin, Canadian Arctic Archipelago.
Calcite cements from the Upper Paleozoic sequences 2, 3 and 4 of the Sverdrup Basin (Canadian Arctic Archipelago) are the subject of this study. On a micro-scale, petrography with light microscopy, cathodoluminescence (CL), scanning electron microscopy (SEM) and staining helped to identify two main …
