Depending upon how many bags you’re mixing at one time if you were doing two at a time that’s 58 bags or 58 mixes if you make the first 20 mix is a little wetter and taper down down from there you should be OK if you’re doing it around this time of the year if you’re doing it when it’s hot outside not really recommended to do with that way at that point you should probably split the poor weather in the beginning and taper down to not so wet at the end should help you out
How thick are you pouring in order to know how many bags you need I need to know how thick you are pouring the concrete
I don't know how thick the slab has to be but when you find out you can use the concrete calculator available on line to determine the number of bags.
22 of the 80 pound bags I used the Sakrete calculator: https://www.sakrete.com/product-calculators Note this is 1760 pounds to move. A rental mixer is suggested.
No, I cannot tell you how many bags you need. But I can tell you Sakrete has a concrete calculator on their website, you put in the length, width, and thickness and it will tell how many bags you need for your project good luck.
No, this will break apart on a thin pour and driving on it. There are products made just for what you want to do.
Use the concrete calculator available on line.
For a slab that is 70 feet x 12 inches x 18 inches deep, you need 175 of these 80 lbs bags
Yes, it will work fine for that purpose.
