Durability properties of marine sediments stabilised by pozzolan and alkali-activated binders / Makiko Obana in European journal of environmental and civil engineering, Vol. 16 N° 8 (N° Spécial) (Septembre 2012)

Attempts have been made to use marine sediments e.g. in the construction of pavements and driveways. Hence, methods to stabilise marine sediments have recently been developed. A new approach to sediment stabilisation is here proposed by using pozzolan and alkali-activated binders. Freeze–thaw and wet–dry tests are conducted to determine the durability of the sediments and to examine their suitability for use as construction material. The binders are prepared by alkali activation using pozzolan, and different amounts of the binders are mixed with marine sediment. The surfaces of one group of sediments are treated by a substance containing liquid glass. We compare the durability properties and deformation behaviours of two different types of specimen, by conducting tests and taking into consideration climatic conditions. The sediments stabilised by surface treatment showed high durability properties.
