# 3
cement:sand= 1:5
for 1cum= 1/6
=0.166
so cement for 1 cum=0.166cum
but volume of 1 cement bag is=.033cum
bag required per cum is=.166/.033
=5 bags
sand required is=0.166*5
=0.833 cum

# 4
cement per 1cum 1:5=(1.1*1440)/5=316.8kgs or 6.4 bags
sand per 1 cum 1:5=(6.4bags*1.25*5)/35.315=1.13cum
(including Bulkage)

Let Area to be plastered=100 m^2
& Thickness of plaster= 12mm=(12/1000)m= 0.012m
Volume of mortar required= 100 x 0.012= 1.20 m^3
Add 20% extra mortar for filling joint,depressions and
wastage.

Volume of the mortar= [0.20 X 1.20]+ 1.20=1.44 m^3
[Wet Volume]

Increase further by One-third of the volume to get Dry
volume
Quantity becomes= [(1/3) X 1.44]+ 1.44=1.92 m^3

Summation of proportion=1+5=6
For 12mm plastering in 1:5 cement:sand mortar mix,

1)Cement required= 1.92/6= 0.32 cu. m
No. of bags of cement= 0.320/0.0347=9.22 bags
>>9 bags(say)
Kgs of cement required=9 x 50= 450 kg (approx)

2)Sand required= [1.92 x (5/6)]= 1.60 cu. m

[Weight of 1 bag of cement= 50 kg
Cement should be always measured by weight to avoid
variation.

One 50 kg bag of cement weighs 1440 kg/cu. m
Volume of 1 bag of cement= 50/1440=0.0347 cu. m ]

Therefore to convert Cu. m into No of bags of 50 kg
cement,just divide the volume of cement by 0.0347

suppose area=100 sft
ratio 1:5
sum of ratio is 1+5=6
for cement=1/6*100=16.666
so 16.666*1.54=25.666
for cement bags=25.666/1.25=20.5333
so say 21 bags of cement

for sand=5/6*100=83.333*1.54=1.28

Each and every 1 s making mistake of Shrinkage factor,,
that s 1.5
So then

ratio 1:5
sum of ratio is 1+5=6
for cement=1/6*Quantity*1.5= X
so
for cement bags= X /1.25= Y

we get Y bags of cement

for sand=5/6*Quantity*1.54= Z

# 10
c:m ratio for plastering (1:5) for 1 cum

sand 1cum = 1.25cum .... constant in all ratios

cement 1cum = 1.25 x 1440
------------ = 360 kgs = 7.2 bags
