Job Mix Concrete Volume
Posted in Concrete Engineering |

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.
THANKS A LOT ACTUALLY THIS REALLY HELP ME A LOT BECAUSE I WORK IN THE READY MIX CONCRETE BATCHING PLANT AS OPERATION MANAGER AND THANKS FOR YOUR FORMULA RE:JOB MIX CONCRETE VOLUME
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

It’s very imported for our company and i want to know better than and value about mix design.
dear all,
i has work exp in site but i am week in mix design can u help me
Dear all,
I dont have experience in using the formula ..
Can u pls help me how to use the formula for getting volume of cement for 1m3 of concrete…
sir i am fresher civil engineer sie can u help me how t use this formule by any examples..
in job mix formula no need to consider sand bulkage;
Dear Sir
Pls give me details concrete super Plasticizers name and with composition.
2: what is means of Old and cold concretepls give me details.
Thanks

It is good &interesting concret. PleaseWould you like to Fined job for me Alemayehu (Ethiopia).immidiate Response I need
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
please send me procedure for desiging of multistoried buildings
can you send me the procedure of concrete mix design including it’s formulas
How to mix the buildig concrete? What is the standardaized formula?
really i need the names of cement test
