I have a 1 sack mixer and it has mixed alot. The problem is I'm tired of screwing my back up for weeks after a pour (I think this is where wisdom comes in) I use 5 gal. buckets of sand to load the mixer. A bag of portland will fill 2 buckets and 10 buckets of sand makes a 5 sack mix (fine for sidewalks). I am going to build a small combine bin so I can use the loader to fill it. I need to make sure my math is right. I don't have scales so I use volume to get the right mixture.
A bucket is 11" dia x 13" deep. one bucket holds 1235.431 cu in X 10 buckets =12354.31cu in convert to cu ft is 7.149487. Is this right?
Now the bin will hold 7cu ft of sand so I just back the mixer up to the bin and open the gate to fill slowly add water and portland and my back won't get me down.

Doesn't it depend on grain size when converting from cu in to cu ft?

Hey guys

Don't forget cement comes in bags and is a powder.

Concrete comes out of a mixer and is the wet stuff.

Just a pet hate from a construction type /w3tcompact/icons/grin.gif

FWIW, a lot of the strength of concrete is from the aggregate. An all sand mix won't be that stong.

Ain't it 3-1? 3 parts sand to 1 part concrete mix?

Helpful hillbilly hint. Toss in a few shovel fulls of gravel. Makes the stuff got much farther! I learned more about the stuff in a week than I want to know.

I thought the mix was 1-2-3, 1 part cement, 2 parts sand, and 3 parts gravel. I could be wrong though.

That's the formula I always heard - but you couldn't prove it by me - mine always comes right out of the truck all wet and ready.

I thought we were talking about concrete.
