The weight of a concrete 80 lb bag is 80 pounds.
This all depends on the mix you want. I assume you mean cement when you mention the 80lb bag of concrete. I have pushed concrete in my day... Bag cement mix is the same as concrete. Don't be funny. How many 80 pound bags will make 1 yard of concrete? I want a definitive answer this time.
P.S.- how did you find this out? Do you weigh 80 lb. bags of cement for fun? rofl ^_^
