Concrete and cement?

Question

the ready mix concrete has a 90 lbs. bag and a 60 lbs bag. how many cubic feet will each bag cover? and the same goes for the cement.--yes there is a difference

Answer 1

That depends on how much concrete your poring?  If you make a 6 inch driveway you lose 2 inches per foot times 12 times 12 or 144 sq inches of concrete.  If you pour a sidewalk at 4 inches you get more footage out of a bag of concrete.  Now what was your question again?

  I got carried away with cement shoes and I was thinking mafia or something ...oh well.

Answer 2

the 60 lb. bag of pre-mix will do 2/3 of a cu. ft....haven't seen 90 lb. bags of pre-mix...a 96 lb. bag of cement will depend on the strength of mix you want...for a six bag (3500 lb. mix) you would get 1/6 of a yd. or 4.5 cu. ft...
