ENVIRONMENTAL IMPACTS ON SEAWATER DUE TO CASTING CEMENT TREATED SOIL UNDERWATER

Abstract

Cement treated soils are often cast underwater in coastal constructions. If the soil separates seriously during the process of underwater casting, there is the possibility to result in environmental impacts on the surrounding water. Underwater casting methods of cement mixed soils are explained. Practical examples by compelled casting method are presented. This method is to cast cement mixed soil underwater by erecting the casting pipe into the freshly cast ground and to expand it silently. Turbidity and pH actually observed in projects are also reported.
