Abstract: A large-scale perimeter bund was recently constructed using PM-CLAY METHOD in south-east Asia. For this project, an unprecedented volume of 3,000,000m3 pre-mixed clay (hereafter,”PM-CLAY”) was placed at a level 30m below sea level.
This method uses PM-CLAY (a mixture consisting of natural clay, water and cement) as a construction material, which is useful for reclamation, revetment and perimeter bund.
The PM-CLAY METHOD has many special features. Especially, it can produce various desired materials to cope with each particular construction purpose by adjusting water and cement in according to the characteristics of the natural clay. As PM-CLAY consists of fluid materials, it can be used without additional soil improvement works.
In this project, the perimeter bund was constructed with an inclined face of eighteen degrees (1:3) by direct placing of PM-CLAY without using any mold. The PM-CLAY METHOD also helped reduce the local procurement of construction materials at the site area as it uses PM-CLAY that is the mixture of natural clay, water and cement.
Hence we introduced construction of the perimeter bund using the PM-CLAY METHOD.
