Preparation and Mechanical Properties of Graphene Oxide: Cement Nanocomposites

The Scientific World Journal, 2014
We investigate the performance of graphene oxide (GO) in improving mechanical properties of cement composites. A polycarboxylate superplasticizer was used to improve the dispersion of GO flakes in the cement.

Self-Compacting Mixtures of Fair-Faced Concrete Based on GGBFS and a Multicomponent Chemical Admixture—Technological and Rheological Properties

Buildings
The use of superplasticizers in a self-compacting concrete mix without the addition of a foaming agent in practice leads to a well-known problem associated with increased air entrainment and promotes the formation of harmful large bubbles, high-void ...

Property enhancement and mechanism of cement-based composites from the perspective of nano-silica dispersion improvement

Case Studies in Construction Materials
Nano-silica (NS) exhibits significant potential for enhancing the properties of cement materials. However, its effectiveness in improving the properties of cement-based materials is hindered by the poor dispersion of NS within the cement matrix.
