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./>

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.
john bromwich
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
Gopal Mishra
for 15MPa, as per Indian code, its mix ratio is 1:2:4, and for this mix, it is shown in the above table that, cement required is 310kg of cement or 6.2 number of bags of cement, 0.434 cubic meter of sand (FA) and 0.868 cubic meter of coarse aggregate or stone.
similarly, for M20 or 20MPa concrete, refer above table with mix ratio of 1:1.5:3, you will find, 395 kg of cement or 7.9 bags of cement, 0.414 cubic meter of sand (FA) and 0.828 cubic meter of stone (CA).
I hope this clears the doubt.

What is the F factor in batching concrete ?
I always was told the Ffactor 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:
F15: so 15 x 25 = 375 kg cement/ cub.meter
For 30 mpa we use F14. 14 x 30 = 420 kg cement/cub.meter
Etc. All by WC ratio of 0.50.6
Is this formula wrong or what.
I am confused now.
Gopal Mishra
I know the thumb rule to calculate the cement content of concrete mix per cubic meter. i.e. for ratio of mix 1:x:y, divide 44 by (1+x+y)
i.e. cement content required in bags = 44/(1+x+y)
for 1:2:4 (M15), cement content = 44/(1+2+4) = 6.2 bags = 310kg of cement
for 1:1.5:3 (M20) cement content = 44/(1+1.5+3) = 8 bags = 400 kg.
in your example, you are getting only 320 kg for M20, which i think is the old formula. After IS 456:2000, old M20 is now equivalent to current M15. i.e. ratio 1:2:4 is now M15.

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?

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!

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).
Rama Sarma
This is nice. piece of information to daily routine jobs. Very useful info.
Michael Pitogo
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.
