Abstract The interest in inorganic foundry binders has been rising steadily recent times due to their favorable environmental characteristics. This paper compares the mold quality and cast attained with different binders. Three types of sand five were used for study. Of binders, there was liquid sodium silicate hardening methods, a geopolymer binder, also solid silicate. assessed through bendin...

While soluble silicate binders have been used effectively for decades in various end uses, recent developments and discoveries may improve and expand the use of silicates. This paper reviews the traditional use and chemistry of sodium silicate binders and also describes how surfactants, viscosity modifiers, lubricants and non-traditional setting agents can provide new characteristics and flexib...

Water based inorganic alkali silicate binder of zinc rich primer was modified by adding acrylic resin derivatives. Several series of primer coatings were formulated by adding 5, 10 and 15 wt of acrylic and acrylic/styrene copolymer to potassium silicate binder and used as binder in zinc rich coatings. The formulated primers were applied on low carbon steel plates and the corrosion protection pr...

Sodium silicate solutions are used as an eco-friendly binder in the casting process. However, strength of sand molds using sodium is reduced because their low humidity resistance. In this study, silica nanoparticles were added to a solution with constant SiO2/Na2O ratio improve resistance inorganic binder. The effects dissolution times and particle size on flexural was also investigated. physio...

A model that makes use of the cooperative organization of inorganic and organic molecular species into three dimensionally structured arrays is generalized for the synthesis of nanocomposite materials. In this model, the properties and structure of a system are determined by dynamic interplay among ion-pair inorganic and organic species, so that different phases can be readily obtained through ...

Since the emergence of problem nuclear waste conditioning, cementation has become an important and developing part management system, owing to its simplicity versatility. The continued development technique is driven by improvement expansion cementitious materials that are suitable efficient for solidification. Advances in cement theory technology have significantly impacted improvements techno...

We evaluated the use of ion-exclusion chromatographic systems for analyzing the behavior of inorganic ions (e.g., bicarbonate, sulfate, chloride, nitrate, phosphate, dissolved silicate, sodium, ammonium, potassium, magnesium, and calcium ions) in a suburban river located in Jakarta, Indonesia. Carbonate, phosphate, and silicate ion concentrations were determined using ion-exclusion chromatograp...
