Are there any more sustainable types of concrete mixes available and, if so, what sort of premium do they come in at?

There are some cements that are supposed to be carbon neutral.

Spoke to this guy a few years back, was very helpful.

Not sure if he is still at Sheffield.

And, can you source them locally ... 

I mentioned sustainable concrete once in the pub  : the laughter only died down after I had bought a round

It is not the filler, it is the cement that is the problem.

How much can you reduce the usage to. That will probably give a greater saving.

It go for lime. 

Mix and pour.

Wait a year.

Repeat process.

A few companies that I've heard of but not used. Well, except for building a shed base from Hanson Regen mixed cement but that's not really comparable. I've seen up to 50% GGBS specified on larger projects but with a structural engineers input. According to Hanson you can substitute as much as 70%. They have a UK technical line. Sorry, can't help with costs.
