Coal *** Heaps

[HongKongphooey]

Having just past Ferrybridge power station this afternoon on the A1 we saw the enormous piles of waste coal *** heaps. Can they be utilised for anything, and if not what does the power station do with all this waste coal?

Modern uses[edit]

Ground granulated *** is often used in concrete in combination with Portland cement as part of a blended cement. Ground granulated *** reacts with water to produce cementitious properties. Concrete containing ground granulated *** develops strength over a longer period, leading to reduced permeability and better durability. Since the unit volume of Portland cement is reduced, this concrete is less vulnerable to alkali-silica and sulfate attack.[citation needed]
This previously unwanted recycled product is used in the manufacture of high performance concretes, especially those used in the construction of bridges and coastal features, where its low permeability and greater resistance to chlorides and sulfates can help to reduce corrosive action and deterioration of the structure.[3] The *** can also be used to create fibers used as an insulation material named *** wool.

Are you sure it was stockpiles of coal to be burnt?

Round here in the Kent coalfields, the whole sites are now given over to country parks and other recreational sites, with business parks built on others.

When they have finished with them they can turn them into Greenways. That's what they've done in Stoke. Lots of footpaths up big green mountains.

Thanks all, you learn something new every day! Wouldn't have thought it was stockpiled coal waiting to be burnt, as surely it could be easily nicked. Sorry... now i'm showing what sort of down at heel area I was brought up in, if it wasn't nailed down it was nicked...lol
