Need assistance. I have an existing concrete slab about 5'X8' that I need to extend to roughly 10'x13' for a shed. The new slab will be L shaped. and by my caculation be 90 sq ft, and require slightly over 50 bags of concrete to complete.
My question is am I crazy to try to mix 50 bags of 80# mix. I dont have a real good way to get any already mixed in, as its at the back of a yard, up a hill, and trough a small gate.
Should I pour two seperate peices? Is there any way to slow the set time up on the concrete so it doesnt set up before I have it poured? Appriciate any thoughts
