Dick, I hope your retirement is going well for you. I have only been retired for 6 months or so and am still getting settled into the new life. Building and equipping this workshop has been a long term dream and knowing that all the money I will ever earn is already in the bank encourages me to get on and do things now.

I have a tiny bit of possibly pertinent info on the concrete thing.
When I poured the slab for my garage (28'x32' and 7 inches thick) I could pay an extra.. I believe it was 10 dollars pre truck for the 3500lb vs 2500lb concrete.
THe thing I found that was surprizing.. the guys driving the truck all had with them a box about 2' square full of chopped fiberglass. And for some small amount of money they would add the entire box to the mix of concrete. To prevent cracking supposedly.
15 years later it still has no cracks (im knocking on my wood desk)
From the people I have talked to since. the generic chopped fiberglass mat helps a ton in preventing cracks. Granted. Im in FLorida.. so it doesnt get below freezing very often.. so that may help.

John Hill:
Thanks Scott, there are a number of options for reinforcing and thats one of the items to be discussed with the concrete caster. I sure hope my workshop never goes below freezing, although we have frosts here my workshop is part of the house.

Just a point,
You cannot add just ordinary glass fibre to concrete, :hammer: it needs to be an Alkaline Resistant Glass.
