Quantity of materials such as cement, sand, coarse aggregates and water required per cubic meter of concrete  and mortar for different mix proportions varies with the mix design of the concrete and mortar respectively.

Following table gives the estimated quantity of materials required per cubic meter of mortar and concrete for various nominal mixes.

Quantities of Materials Per Cubic Meter of Concrete Mix Proportions

Notes:

1. F.A.= Fine Aggregates, C.A.= Coarse Aggregates

2. The table is based on assumption that the voids in sand and crushed stone are 40 and 45 percent respectively.

3. Air content of 1 percent has been assumed.

4. For gravel aggregates decrease cement by 5 percent, increase sand by 2 percent and coarse aggregate in proportion to fine aggregate in mix.

4. No allowance has been made in the table for bulking of sand and wastage.

  1. there is no exact quantity on how much water u should sprinkle on the structure once u start curing the concrete… The sample once it settled at 24 hrs after casting, is immersed to the curing tank until the time of testing (28 days). From there u can deride that the structure should be all throughout wet to attain the needed strength at 28 days.

  2. This is nice. piece of information to daily routine jobs. Very useful info.

  3. Any one tells me How we can calculate the Quantity of Water required for concrete curing Per Sft/Sq.m OR Per Cu.m/Cu.ft Per day(7 days,14 days OR 28 days etc).

  4. the cost per cubic meter vary from country prices. E.g, the cost of cement in your country is different from my country. All you need to do is to get a Q.S that has built the rates per cubic meter in your country to tell you. I in Ghana has my rate per cubic meter. Cheers!

  5. plzzzzzzzzzz give the ans how much river sand is going in 600 beg cement plzzzzzz give me full ans how to do it

  6. dis is very nice but i stil need to know the cost per cubic meter

  7. This is nice if you also, post a table of Water/Cement ratio in function of concrete resistance at 28 days. With this data, you cant calculate accurately a concrete with the resistance as an unknown.

  8. What's the strength of each of these concrete mixes?

  9. How many grams of Air content admixture is needed to one cubic meter concrete?

  10. We are looking for pricing on:

    We are working on a tender for a low cost housing development in Lagos,

    Nigeria and wanted to ask you if you would be able to price the following:

    a) 25Mpa/ 19mm stone – pump mix concrete – Rate /m3.

    b) 25Mpa/ 19mm stone – regular mix (75mm slump) – Rate/m3.

    c) 15Mpa/ 26mm stone – pump mix concrete – Rate/m3.

    d)15 Mpa/ 26mm stone – regular/ 75mm slump concrete – Rate/m3.

    e) 30 Mpa/19mm stone – pump mix concrete – Rate/m3.

    f) Establishment costs and rate/m3 for a telescopic boom pump – 36m length.

    boom

    g) Cost of aggregates – 13mm, 19mm, 26/16mm concrete stone; river sand;.

    building sand; plaster sand – Rates for all of these per m3.

    If you would be able to work these out based on an initial volume of a.

    minimum of 2000m3.

    Can you assist or point us in the right direction?

  11. Dear Sir,

    Please send me different types of civil quality tips in water project its help full for site

  12. this is all many need to improve on their careers.thank you very much for this site.God Bless You.

  13. It is really a home, a destination point, a reference site and a library for civil Engineers. Keep the flag flying.

  14. How to calculate the quantity of cement used in cured concrete block of 1:2:4 ratio. My aim is to understand the volume reduction if any after the concrete is set.

  15. What is the F- factor in batching concrete ?
    I always was told the F-factor basic was F 16
    Being a rule of the thumb calculating the amount of cement per cub/meter
    With a starting point of 20 mpa – being F16
    Calculated as follows:
    16 x 20 = 320 kg cement for 1 cub meter of concrete by 640 kg of sand, and 1200 kg aggregate
    Now for every 5 mpa increase in strength we drop the F factor by one
    So for 25 mpa the formula becomes:
    F-15: so 15 x 25 = 375 kg cement/ cub.meter
    For 30 mpa we use F-14.  14 x 30 = 420 kg cement/cub.meter
    Etc. All by WC ratio of 0.5-0.6
    Is this formula wrong or what.
    I am confused now.

  16. 30meter length,13metre breadth and 0.1metre height floor howmany materials requeired for this construction

  17. i want to know that the quantity of mortar required for one cubic meter rubble work.

  18. i want stone QTY per cubic metre so i calculate stone masonry

  19. i need to know the breakdown and ratio for 20 and 25mpa cement mix, and need to know how much cement, sand, stone and water per cubic meter and may assist me with a table.

  20. help, please tell me number of 50kg pockets of cement and cubic metres of river sand (FA) and stone (CA) or part cubic metre thereof respectively for mixing one cubic metre of concrete for a 15mpa and 20mpa strength respectively regards John

  21. number of 50kg pockets of cement and cubic metres of river sand (FA) and stone (CA) or part cubic metre theireof respectively for mixing one cubic metre of concrete for a15 mpa and 20mpa strength respectively.
