In situ
and pre cast concrete
Concrete lends itself well
to forms of construction that control temperature through thermal
mass -see the BPCF site for some useful downloads on the benefits
of thermal mass. However Portland Cement is less sustainable
-in fact Cement production has been recorded as the third ranking
producer of CO2 in the world after transport and energy generation.
The impact can be reduced by
using cements incorporating Pulverised Fuel Ash (PFA), or 'Fly
ash', a by-product of burning coal in power stations or Ground
Granulated Blast-furnace Slag (GGBS), a by-product of the Iron
industry.
Consider use of limecrete (lime
recycles C02) instead of concretes based on Ordinary Portland
Cement.
Use of recycled aggregate and
steel reinforcement further reduces the impact.-see theAggregain website for more on this. Of course
if you can recycle the aggregate on site from demolition works,
then that is an ideal solution.
