    Why use this and not just cheap cement?

    I prefer (where practical) 20% portland cement mixed with 80% GGBS (steel works slag which otherwise goes to landfill).

    It produces a mortars and concretes which is more durable than straight protland, with reduced thermal stress from curing, and better waterproofing, with higher strength too. Downsides are longer set times at low temperatures, and higher bleed rate. Alternatively 50/50 OPC/GGBS is pretty much plug and play (40/60 during summer months), and it's what Hanson will give you if you just go and ask them for ready-mix concrete.

    GGBS is cheaper in bulk than portland, but harder to source in small quantities. It does have a much longer shelf life than portland tho'.
