Job Mix Concrete Volume

posted in Concrete Engineering | Email This Post Email This Post

A trial batch of concrete can be tested to determine how much concrete is to be delivered by the job mix. To determine the volume obtained for the job, add the absolute volume V a of the four components—cements, gravel, sand, and water.

Find the V a for each component from

V a = W L / ( SG ) W u

where V a = absolute volume, ft 3 (m 3 )

W L = weight of material, lb (kg)

S G = specific gravity of the material

W u = density of water at atmospheric conditions (62.4 lb/ft 3 1000 kg /m 3 )

Then, job yield equals the sum of V a for cement, gravel, sand, and water.

    Im searching this formula for how many weeks, in the internet thanks a lot for the posting.
    Actually I have a pocketbook reviewer (Besavilla) and it is states only direct to the
    computation I want proof or either formula, which I found here. You know as a civil enginner
    sometimes our clients or friends ask us ‘How many volume of concrete can one bag of cement
    produce? Because I forgot already this formula. For the second time thank you very big.

    Dear All,
    I just start working in Concrete company, I had no experience with the formula in making /mixing all material, Is it possible to get the standart mix design for Quality 225 (that’s haw we called in Indonesia).

    Your information will be highly appreciated.

    Thanks,

    Daniel
