first of all We should conseder in our colculation the
ratio of cement,Sand , aggregate and water cement ratio
which we have received from mix design test

Answer / kunal

how to calculate FA & CA in KG...? pls Give me ans i dont know...

Answer / rahul mehta (g.m. projects)

M30 design..Cement:1/4*1.54=.385*28.8=11bags per cuM,Sand:.385*1=.385cuM,because dry density 1.54=wet density 1.54 in concrete work

Rectangle, etc.,). Which shape will covers
maximum area
1 Newton = o.101971 kg
1 mm2 = 0.01 cm2
1 cm2 = 100 mm2
1 mm2 = 20 N
100 mm2 = 2000N
1 cm2 = 2000N
2000 N = 203.942 kg
So 20 N/ mm2 = 203.942 kg / cm2
RATIO IS 1:1.5:3
then volume is 1+1.5+3=5.5 and the total volume

2000 N = 203.942 kg
So 20 N/ mm2 = 203.942 kg / cm2

Answer / prakash pandiyan

for designing 1m3 concrete of M25 mix the ratio is 1:1:2
for calculating cement,sand and course aggregate ,
for 1m3 add 50% for shrinkage and wastage so 1.5m3
1.5m3/(1+1+2)=.375
density of cement =1440kg/m3=says 1440/50=28.8bags
cement required for this mix=.375*28.8=10.8bags
sand=.375*1=.375m3
course aggregate=.375*2=.75m3
FINALLY WE SAY 10.8 BAGS/M3

Answer / misal dinesh

Take The Ratio - 1:1.5:3
For 1 cu.m wet volume consider its dry volume 54% more
i.e = 1.54 cu.m of concrete.
Total Volume of concrete for Mix= 1.54/1+1.5+3 = 0.28 cu.m
Total quantity of cement for Mix= 0.28/1 = 0.28 cu.m
Total quantity of cement in bags= 0.28/0.035 = 8 bags
Total quantity of Metal for Mix= 0.28/1.5 = 0.187 cu.m
Total quantity of sand for Mix= 0.28/3 = 0.093 cu.m

Answer / akheel

plz explain this

Answer / amaresh jamadar

As per my observations ,the end concrete or dry concrete should be,
Total weight of cc=2300 kg/ cu.M
Ratio m-20=1:1.5:3
So weight of cement=2306/(1 1.5 3)=2306/5.5=418 kgs or 8.36 bags
Weight of sand=418*1.5=627 kgs or .392 cu.M
Weight of ca= 418*3=1254 kgs or 0.76 cu.
M
Correct me if am wrong.

Answer / aryan

Sorry for that
Why I am using volume of dry wet concrete 1.54 to 1.57
Or
How we know the volume of dry wet concrete

Answer / tukuna das

M30 means , proportion 1:1:2 , so that

Total Volume = 1m3
we take 52% extra for dry volume , miss handling etc then ,
total volume = 1* 1.52 = 1.52 m3
Quantity of cement required = 1.52/(1+1+2)=0.38/0.035= 10.857bags = 11 bags
Quantity of sand required = 0.38*1=0.38m3
Quantity of aggregate required = 0.38*2 = 0.76m3
