@LasagnaIsGood The answer to this is summed up in the beginning "You take calcium carbonate and you heat it up to create calcium oxide or lyme". It takes a lot of energy to heat up the limestone to the point where it becomes lyme. Energy prices are on the rise so concrete prices fluctuate with energy prices. Then there is the cost of moving a heavy substance to the place where it is to be mixed and then from there where it will be poured. Try shipping 100lbs of rock interstate.

A- concrete continues to harden throughout its life
B- you can pour concrete directly from the lorrie underwater, a boat launch is an example of this, water is actually used on factory floors to slow the evaporation and potential cracks.

@LasagnaIsGood Let us say we found a way of utilizing the surface dust of the moon for building houses. You could still say "We will never run out", but it is still an expenssive process of getting the moon dust. So I don't see how the "we will never run out" is linked to the pricing in this case. Well, it sorta is. If on the same time it was a rare product, concrete, it would be even more expenssive :)

@LasagnaIsGood it's an expensive process to make it

WHY THE FUCK IS IT SO EXPENSIVE WHEN YOU WILL NEVER RUN OUT!?!
