Experimental Study on Laterite Eroded by Alkaline Materials

Abstract:

Laterite contacted with alkaline materials, was significantly corroded under same conditions, it to be found in the processes of dam safety identification. Alkaline materials properties and acid-alkali reaction were analysed, and supersaturation emulsion calcium hydroxide was used to immerse laterite at constant temperature. Then changes of ion concentration were detected in exudates, change trends of grain size gradations were analysed, and evolutions of pore were observed in laterite. Mechanism of laterite chronically eroded by alkaline materials is opened out, which is neglected by engineers and has become one of the main reasons why reinforcement benefit is always too low.
