An experimental study on foamed concrete foundation as peat soil replacement in sarawak

This research is concerned with the prospects of using foamed concrete as fill material (which will be referred as foamed concrete foundation in subsequent sections) on peat land based on the density replacement method. This study adopted the concept of "floating foundation" where the dens...

Sanitary engineering This research is concerned with the prospects of using foamed concrete as fill material (which will be referred as foamed concrete foundation in subsequent sections) on peat land based on the density replacement method.
