Posted. I wonder if adding Epsom salts (dissolved in water) would improve the plasticity of clay contaminated with sodium silicate. I've found that this works for clay that's been deflocculated with sodium polyacrylate (aka Alcosperse aka Darvan). Posted. Well, I'll give the Epsom salts a try this week--good suggestion.

The sodium silicate, which has many advantages as a healing agent in cementitious materials, can be encapsulated through the interfacial polymerization of shell-forming monomer on the aqueous sodium silicate droplets. This study, which is a part of comprehensive project, aimed to produce these microcapsules by optimization of the …

In a solution, sodium silicate gels form particulate solids when in contact with divalent ions, such as calcium (an internal-activating catalyst) or cement. 2 When the water phase is squeezed into ...

Sodium Silicate is a chemical compound that has properties such as water glass is a colorless, soluble in water, and is widely used in industry. Therefore, the extraction of sodium silicate by alkaline fusion is followed by water leaching. The alkaline fusion process is a technique that is often used and can further simplify the extraction process.

Flame-retardant coatings have drawn much attention in recent years. In this study, an inorganic sodium silicate-based intumescent flame-resistance coating with an excellent flameproof properties is developed by mainly utilizing sodium silicate as the ceramizable binder, via hydrolysis and self-condensation reaction. Fly ash, metakaoline, …

Two types of sodium silicate microcapsule, which differed in their polyurea shell properties, were first evaluated on their suitability for use under the high …

Abstract. This paper reports the formation and structure of fast setting geopolymers activated by using three sodium silicate solutions with different modules (1.6, 2.0 and 2.4) and a berlinite-type aluminum orthophosphate. By varying the concentration of the aluminum orthophosphate, different Si/Al-ratios were established (6, 3 and 2).
