Development of a co-dispersion binder for the three-dimensional printing process to facilitate handling of ceramic casting shells in the green state
… by selectively depositing a colloidal silica binder. Firing fuses the silica to the alumina, and subsequent processing removes the unbound powder from the casting cavity. In some instances, it may be advantageous to perform powder removal before firing. This requires higher green strength than …

Improved sol based ceramic moulds for use in investment casting
… network. The structure and distribution of the binder is also established and this indicates that the major load bearing points within the mould consist of thin areas of silica. As such, the overall performance of the mould is directly related to that of the silica itself. This binder is shown …

Development of Two Novel Families of Platinum(Ii) Coordination Complexes for Nucleic Acid Recognition
… DNA. In fact, they can also self-assemble into alternative higher order architectures, such as guanine quadruplexes (G4s). These four stranded assemblies have risen to prominence as promising drug targets as a result of their demonstrated relevance and enrichment in genomic regions involved in …

Evaluating shrinkage of fly ash - slag geopolymers
… in order to evaluate geopolymer as a sustainable alternative binder. This study will help in evaluating the mechanical behavior of geopolymers when used in field. Since shrinkage causes volume change, any volume change after the binder has stiffened will cause stresses to develop and this will …

Understanding the role of slag on geopolymer hardening and microstructural development
… for successful application of geopolymer as an alternative binder. The early age properties like hardening (stiffening) and setting will determine the removal of formwork and thus the time of construction. The study was performed on user-friendly geopolymers obtained by using Class F …

The Chemistry of Dimethacrylate-Styrene Networks and Development of Flame Retardant, Halogen-Free Fiber Reinforced Vinyl Ester Composites
… and carbon monoxide. A series of halogen free binder systems has been developed and dispersed in the vinyl ester to improve flame retardance. The binder approach enables the vinyl ester resin to maintain its low temperature viscosity so that fabrication of composites via Vacuum Assisted Resin …

On the Development of 8,000 psi Geopolymer Mortar for Practical Use in Field Applications
… perceived benefits from the use of geopolymer binder as an alternative to ordinary portland cement in concrete materials, it is not widely used in field applications. Geopolymer materials have no set guidelines for mixture design and often require heat curing to facilitate strength gain. …

Setting and nanostructure of slag-fly ash binders
Slag fly ash binders (SFB) are room temperature hardening binders that have high strength, reasonable setting time, and lower carbon footprint when compared to ordinary Portland cement (OPC). The precursors for SFB are industrial byproducts, namely slag and fly ash. The inexpensive nature of the …
