Resumen de Rising tide for olivine in underwater concretes
While the addition of nano-silica to concrete mixes is less developed than underwater concrete technologies, Vetoulas said that Grecian Magnesite is performing extensive research and development (R&D) work into developing the material as an additive for high performance concretes, in a process that requires olivine and sulphuric acid as raw materials.
2Mg[subscript]3 Si[subscript]2 O[subscript]5 (OH)[subscript]4 [rightarrow] 3Mg[subscript]2 SiO[subscript]4 + SiO[subscript]2 + 4H[subscript]2 O Slag conditioner grade olivine prices are "much lower than for olivine used in refractory applications", [Vetoulas] said.
