Aggregates

Re: More granularity required

Ah yes, but my figures are entirely based on the greater granularity of the remaining 16.3% owed to me by a nigerian foreign minister by the name of bob

Re: More granularity required

FFS Brendan, you been cruising round the medicine cupboard tonight? OK it was crap, but aggregates, concrete, granularity, errmm, oh never mind, it was a just mildly shite play on...............

I have the utmost respect for your opinions on matters electrical, but you have given us statistics, which, on the basis that 83.7% have been made up on the spot anyway, lack credibility in the provenance department.

Not been in the medicine cabinet, that's what you said.

The later sentence about aggregates wasn't related to the provenance of statistics

More sand and concrete granularity requirement challenged by Brendan.

Sorry Brendan, didn't mean to upset you, TomE picked it up, you didn't. Apologies for that, no offence meant.

Re: More sand and concrete granularity requirement challenged by Brendan.

I did get the latter references, though the early part seemed serious.

Re: More sand and concrete granularity requirement challenged by Brendan.

Nah, not at all. But, just to be terribly serious for minute, there wuz no source... hence... oh bugger, that's how it all started...

Jeez tome, how boring is that? Anything more interesting to report? /forums/images/graemlins/smile.gif

If you want new roads and buildings then the aggregate has got to come from somewhere. Digging bloody great holes in the Home Counties isn't very popular either.
Sustainability is debateable as well, certainly some of those offshore banks were dumped there by glaciers thousands of years ago but millions of tonnes of our coastline is falling in to the sea every year and it must be going somewhere. Chesil Beach is being constantly fed by erosion of the cliffs around Lyme Regis so where does all that gravel go after it leaves Portland? Similarly Hill Head beach (which I know more about) is fed from eroding cliffs between the Hamble and the Meon. The material works its way East and “disappears” off Gilkicker.

Care to give more details of what you'll be involved with ?

Merely reporting developments to members of our institute, as far as I'm aware. But much better to report from an informed perspective IMO

It's only a rumour, but the story is going around that there was a serrated bread knife spotted on one of the dredgers. How much more excitement do you want?

Here's a concise example of construction induced sea bed changes and coastal erosion from Dubai.

As a Civil Engineer I was involved in the desigh of Easington Terminal on the East Coast. Its some 25yrs ago but AFAIR they estimated that erosion by the sea would be 1m pa, It has been 4 to 5 mpa since then. At that time studies were indicating that protecting one area could cause greater erosion elsewhere and any sea defences were looked at and often refused on the basis of let nature take its course.

Currently I believe the authorities prefer to do little protection unless cost effective,

Now the rub, Nature changes over the years and apart from plate movement that forces up the ground- the effect of wind/rain/freezing it to errode all land above sea level and ultimately wash it into the sea. Rocks get moved by water and reduced to pebbles and other rocks get reduced to sand.

If we leave alone, finally, all land will be burried under the sea in x millions of years. To protect the land we have they dredge the sand and pebbles back from the sea and use it to make concrete. Some of that concrete may be used for flood protection and barriers to prevent land errosion. So all you are doing is reversing nature. Yes there are effects whenever you interfere wioth nature. eg Medicine is reversing the effects of natural selection.

The real problem with regard to interfering with nature is that the total amount we now have to do it due to the world population and while we all breast beat about global warming down to dredging aggregates we are not mentally equipped to control the cause of the problem - Population!!

Please excuse all typos but this has been completed without interfering with nature eg I did not wear my glasses!!

Fascinating, thanks. I know those waters well

 

[Blueboatman]

'Population'

Boy isn't that the truth !

In honour of this facinating subject going on and on and on and on and on and on and on........................... I have duly changed my avatar.

Good, I'll leave no stone unturned

Morpeth market place was resurfaced with stone from China.

Whereas Newbiggin sea defence work is using stone from Norway.

Great Britain however is being very green /forums/images/graemlins/confused.gif

 

[tome]

Stone from Norway isn't such a bad idea. Every time they build, they have to dynamite out tons of granite and they must have more spoils than you can shake a stick at

Northumberland isn't a huge boat trip either. Do you know how they use the Norwegian granite, as it's prob a bit big for aggregate?

Brendan, wind yer neck in. I can take care of myself on the forums thanks and Sgeir was merely being flippant
