 The work site at Mack Point in Searsport. The
dredging equipment is visible, as well as a pile of mixed sediment and
kiln dust.
|
 Dredging is underway.

 Close-up of the dredging equipment.
|
 A truckload of dredged sediment is dumped onsite.
The material essentially has a moisture content of 100%, and is completely
unworkable.
|
 This pile contains cement kiln dust that was delivered
to the Searsport site from Dragon in Thomaston.
|
 Bucket loads of kiln dust are removed from the pile.
|
 The kiln dust is carried to the pile of sediment that
was previously dumped onsite.
|
 During mixing, the equipment operator also attempts to
remove all pieces of trash from the sediment (i.e. chains, pieces of wood,
metal, etc.)
|
 The sediment and kiln dust are well mixed.
Multiple bucket loads of kiln dust are added. |
 The CKD is completely mixed into the sediment.
|
 The kiln dust is carried to the pile of sediment that
was previously dumped onsite. |
 Piles of previously mixed material are present onsite.
|
 The dredged material and CKD are fully mixed, and piled
near the center of the mixing site. The material already has a
noticeably lower moisture content.
|
This material already set for a day. The moisture content was around
half what it was when it was first dredged.
|
 To further dry the material, it is spread and rotatilled
at another location onsite.
|
 This material has already been rotatilled. After
it sets further, it will be used for construction onsite or at another
site in Bucksport.
