Ratcliffe Power Station

FABM
PFA was used in an insitu FABM material as a heavily loaded plant construction area at Ratcliffe power station. This area will be used to build the Catalytic reduction units for the power station, to reduce emissions to below those required by the Large Combustion Plant Directive.

A new slip road to access the M1 from the A4211 has been built near Milton Keynes. This slip road was founded on PFA used as a fill material.

Reinforced Earth Embankment

Reinforced earth embankments are not common, especially using fly ash. However, with this technique vertical embankments can be created, as was done at the Wolverhampton Low Level station road improvements.

Reinforced Earth
In this picture they are just beginning to place the first layers of PFA for the reinforced earth embankment...

Plans
The new embankment will be used to take the Wednesfield Road while the old existing railway bridge is demolished and replaced with a further PFA embankment ...There will be a case study about this contract in due, when complete in 2006.

Wind Farms are made with fly ash!

WIndfarm
The many wind farms built in the Scottish Highlands use fly ash based cement from ScotAsh;

Base
This is to reduce heat of hydration and possible thermal cracking problems and to improve durability.

Wind farm do help in the production of electricity and reduce environmental impacts, but using fly ash within the concrete further reduced the impacts of making the wind farm... It full circle!

Ash in other countries

China
China has some massive lagoons for disposal of ash, which eventually become paddy fields, growing rice...

Narva
Some former Eastern Block countries still have some way to go tidy up their act and to utilise their ash!
