Waste Pisha sandstone (WPS) is the main damming material for check dam in Loss Plateau of northwest China. The dissolution characteristics WPS alkaline solutions were investigated as a basis studying modification materials and revealing mechanism to further study pozzolanic activity development cementitious concrete utilizing WPS. In this paper, was milled calcined at 600 °C, 700 800 respective...
Approximately 20% of caustic ingestions result in some degree of esophageal injury. Alkaline materials are the most frequent corrosive materials ingested. The physical form and PH of ingested materials play a critical role in the site and type of gastrointestinal injury (PH > 12 or PH < 1.5, crystalline drain cleaners). Unlike Alkaline solutions, strong acids are bitter, burn on contact and...
To establish the structure of ferric ions in strongly alkaline (pH > 13) environments, aqueous NaOH solutions supersaturated with respect to Fe(III) and the solid ferric-hydroxo complex salts precipitating from them have been characterized with a variety of experimental techniques. From UV measurements, in solutions of pH > 13, only one kind of Fe(III)-hydroxo complex species was found to be pr...
