    Default Makeing cement

    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.

    When I do the calculation I get 7.14948675359 cu.ft. in 10 buckets.

    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 [img]/w3tcompact/icons/grin.gif[/img]

    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.
