1 cu.m= 500 nos Bricks

1 acre= 435670 sq.ft

1 cent=435.67 sq.ft

1 acre= 100 cent

1. How to measure rod wieght?

Answer:

Weight of rod=(D2/162.2)*Length(meter)=kg

2. How to determine how many rod require for a 10ft*12ft footing?Rod spacing 3in in both side.

Answer:

10ft=10*12=120in

Rod require=(120/spacing)+1=(120/3)+1=41 nos

Rod require=(12*12/spacing)+1=(144/3)+1=49 nos.

3. 25cm thick 1.5m inner dia and 6m depth of asoak well.How much construction material require?Ratio 1:6

Answer:

Brick work need=1*{3.14*(1.5+2)/2}*0.25*6=8.24 cum

1+6=7

Dry morter=8.24*35%=2.884cum

Brick need=8.24/(0.254*0.127*0.076)=3361 nos

sand need=8.24*6/7=2.47cum

Cement need=2.884*1/(7*0.0347)=11.87~12bags

4. A soak well 25 cm thick whose inner dia is 150cm and depth is 600 cm.How much cum brick work require for this soak well construction?

Answer:

inner length=3.14*(inner dia+outer dia)/2

=3.14*(150+200)/2=549.5cm=5.495m

brick work need=1*5.495*0.25*6=8.24cum

5. How much construction material require for 10 cum brick work?Ratio 1:6

Answer:

Dry morter=10*35%=3.5cum

1+6=7

Brick need=10/2.54*0.127*0.076=4079 nos

Cement need=3.5*1/7=0.50cum=0.50*1440/50=14.4~15 bags

6.How much construction material require for 12 mm thick of 100 sqmcement plastering work?Ratio 1:6

Answer:

Dry volume=100*12*1.5/1000=1.8

Cement=1.8*1*30/7=7.71~8bags

Sand=1.8*6/7=1.54 cum

Sand need=3.5*6/7=3 cum

7. How Much Construction materials require for 25cm thick plaster of 100 sqm work brick work?Ratio 1:5

Answer:

Brick need=100/0.127*0.076=10361 nos (brick size=25.4cm*12.7cm*7.6cm)

cement need=8.75*1*30/6=43.75~44 bags

Sand need=8.75*5/6=7.29 cum

8. How much construction materials require for 100 sqm cement plastering work of 12mm thick.Ratio 1:6

Answer:

Dry volume=100*12*1.5/1000=1.8cum

Cement req=1.8*1*30/7=7.71~8 bags

Sand req=1.8*6/7=1.54cum

9. For 12m long wall which hight is 3m.The wall thickness is 12.5cm.For 1.5 cm thick plaster for both side of the wall how much cement and sand require.Ratio 1:6.

    Hiya. I noticed your website title, “Basics of Estimation in Civil Engineering | Tobby News” does not really reflect the content of your web site. When writing your blog title, do you believe it’s best to write it for SEO or for your audience? This is one thing I’ve been struggling with simply because I want great search rankings but at the same time I want the best quality for my site visitors.
