Joe,
For some materials on set/cure times see BS 8110,Structural Use of Concrete, one of the Appendices at the end.
Set and cure times are also reflected in minimum times required before striking the form work.
There is a requirement especially for marine structures to prevent the ingress of...
Gents,
I need to instal a concrete barge, plan dimensions 36m*28m in a tidal swamp area,inter tidal range 2.25m, barge will have a free board of 1.0m above high high water mark.
The soil beneath proposed barge location is very soft to organic clays with some organic content to about 15m depths...
Also, for fills a frequent consideration is the attainment of terminal settlement. This is ascertained from a planned settlement monitoring program.
For cohesionless soils, settlement is in the main immediate while for cohesive soils, the consolidation characteristics will provide a guide for...
Nicks/Ang'mac,
This will to all intents not be for you, but can help the forum - you've completed your projects I would imagine,
The basic issue about dredging is relocation of sea bed material for transport access or swamp development construction.

Togel,
Pile thicknesses are actually made up from
* thickness for pile dia./driver/soil combination without buckling- mills and local contractors are a good guide in the absence of a detailed analysis
* an allowance for corrossion based on the chemical analysis of the soil/water
* the...
this is too late in the day maybe, but pile spacing is supposed to take cognisasance of pressure zone influences especially for friction type piles.
while min. spacing is recommended, often 3.14D ie pie *D an optimal spacing is necessary to achieve an economic pile cap.
Spacing requirement is...
