WODCON XX: Land Reclamation by Using Mixture of Dredged Soil and Converter Slag

A lot of dredged material removal has occurred in recent years for maintaining the depth of channels and anchorages.

Also, a lack of the land for the disposal of dredged soil has become a problem.

At the same time, converter slag that has properties such as wear resistance or hydraulic properties has been used as a civil works material in areas such as roadbeds. However, with the reduction of public construction recently, development of new usages is expected.

Therefore, we have developed in coastal areas the utilization of at mixture of dredged soil and converter slag (usually called “slag stabilized soil”). From previous studies, characteristics such as hardening and a suppressed increase in pH is known.

It is used as a material for the “padding” of tidal flats and marine forests, and for backfilling hollows where a large quantity of sand from the sea bottom has been placed for urban development.

Based on an experiment using a pneumatic flow mixing method where slag stabilized soil was used as a material for reclamation, large-scale rapid reclamation work was performed with the aim of satisfying an average strength of 50kN/ nr (long-term curing).

At the same time it was confirmed that there was 110 adverse influence 011 the water quality in the peripheral sea area during the reclamation period.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews (www.portnews.ru) holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
