# Job Mix Concrete Volume

Posted in Concrete Engineering |  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

Requirements of concrete mix design

The requirements which form the basis of selection and proportioning of mix ingredients are :

a ) The minimum compressive strength required from structural consideration

b) The adequate workability necessary for full compaction with the compacting equipment available.

c) Maximum water-cement ratio and/or maximum cement content to give adequate durability for the particular site conditions

d) Maximum cement content to avoid shrinkage cracking due to temperature cycle in mass concrete

sir plz give me information of 1m3 how many cement,sand& aggrigate

• Froilan January 10, 2012 at 10:13 pm

Lokesh,

Depend on the grade of concrete. Usually sand is 44% of 1 cum. and gravel is 88% of 1 cum. Cement are ranging from 12bags, 10 bags, 9 bags per 1 cum. Water Cement ratio usually used 0.40. Hope it helps.
