# 2
10'=3.04m
mix=1:5,
1/6=.1666+25%+30%=.71cu.m of cement

sand requires=3.5cu.m
plastering area=3.04x3.04x0.01=0.092416cu.m

as per thump rule 1:5 mix;

cement - 288 kg.

sand - 3.05*3.05*.01 = 0.093 = 1-0.093 = 0.901 say 1cum

i am not sure the sand calculation any mistake please inform

# 4
as per thumb rule 1:5 CM

3.04x3.04x0.01=.092416 cu.m
since wall is un-uniform ,increase by 30% ie
.092412 + .0277248= 0.120 cu.m
dry volume increses by 25% = 0.12 + .03 = 0.15 cu.m

total volume of mor= 0.15/6 = .025 cu.m
of cement =0.025x 1440= 36 kg cement
sand = 0.025 X 6= 0.15 cu.m

# 5
10sqft=0.9290304m2
volume of plastering =0.9290304*0.010
=9.290304*10-3

total volume of cement =1440/5 *(9.290304*10-3)
=2.67m3

# 6
as per the thumb rule,

quantity of cement required= 0.645 bag= 32.25 kg.= 0.77 cft.
quantity of sand required = 0.77 x 5 = 3.84 cft.

Re: How to calculate the cement, sand quantity for plastering? (10'x10')10mm thick ratio 1:5. wht"s the formula?
# 7
10 feet= 3.05m

area of plaster = 3.05 x 3.05 = 9.3 m2
(convert thickness of plaster into m divide by 1000)
volume of plaster = 9.3 x (10/1000) = 0.09 m3
quantity of cement = 0.09/1+5 =0.09/6 = 0.02 m3
as cement comes in bags of 50 kg therefore volume of one
bag cement = o.0347 m3 (exact)
(or it may be taken 0.034 or 0.035 m3)

no. of cement bags = 0.02/0.0347 = 0.58 bags (almost 1 bag
of cement required for plaster )

quantity of sand = 0.02 x 5 = 0.10 m3

this is exact calculation
you can add 30% extra for wastage etc.

Re: How to calculate the cement, sand quantity for plastering? (10'x10')10mm thick ratio 1:5. wht"s the formula?
# 8
10'X10'=100 sft.
converted in to sqm.=100/10.76=9.29 sqm.
ratio= 1:5, 1+5=6
for cement----1/6 x 1.52=.25 m3 x 35.28=8.93/1.25=7.15
so 7.15 bag in a cum. so for 20mm thk.
for cum. 9.29 sqm x .020 mm = .18 cum.
therefore --7.15 x .18m3 = 1.28 bag answer
for sand------5/6 x 1.52=1.26 m3 x 35.28=44.68 cft./1cum.
so 44.68 x .18m3 = 8 cft answer
1.28 bag of cement
8 cft of sand. required in 10'10 wall with 20mm thk.

# 9
10 FEET =3.048m

3.048*3.048*0.010=0.093cum

sand required =0.093cum(3.28 cft)

Cement req - 1/5*1440*0.093=26.8kg

# 10
Volume of Wet Mortar = 10 mm X 100 sft.

= 10/1000 X 100/10.76 = 0.093 cu.m.

Add 20% for depressions, joints and wastage
= 0.0186 + 0.093 = 0.112 cu.m.

Volume of Dry Mortar = 1.3 X 0.112 = 0.146 cu.m.= 5.154 cu.ft.

Cement required = 1/6 X 0.146 = 0.024 cu.m. = 0.7 Bag

Sand required = 5/6 X 0.146 = 0.122 cu.m. = 4.30 cu.ft.
