Total weight of concrete ingredients = 50+115+209+27.5 = 401.5 say 400 kg. Density of concrete = 2400 kg/cum. So, 1 bag of cement produces = 400/2400 = 0.167 cum. No. of bags required for 01 cum of concrete = 1/0.167 = 5.98 bags ~ 6 bags. From above, if the concrete mix is 1:2:4, to get a cubic meter of concrete we require. 1.Cement = 6 bags ...

Quantity of steel is not dependent on the volume of concrete, but on the structure where it is being used. Slabs: 0.7 to 1.0%, Beams: 1% to 2%, Columns: 1% to 5% It may vary depending upon the loading condition as well For Example Lets take exampl...

Typical average weight of reinforcement (kg/m3) in concrete building elements. The below figures are for guideline only and may vary for different projects. Concrete building element. Weight of reinforcement in kg/m3. ... Commercial = 100 kg/m3 Institutional = 90 kg/m3. Your comments:

4) % of steel volume in Slab concrete = 0.7 to 1.25 % in single mesh. 5) % of steel volume in Slab concrete = 1.4 to 2.5% in double mesh. Lets consider you have column and 3% of steel in column concrete. Desnity of steel rebar= 7850 Kg/m3. Volume of concrete of column = 1m3. Volume of steel rebar in concrete = 3%=3/100*1 =.03 m3. Weight of ...

Then finding out how many packs or bags of dry concrete/dry concrete mix you have to buy for the calculated volume is a bit trickier. So if you want to mix concrete to fill a certain cubic meter and want to know how many bags of 25 kg concrete, 35 kg concrete or 40 kg concrete each can be bought, then you've come to the right place.

In the special civil engineering article, it will be guided in what way to compute Steel quantity for each M³ for Lintel, Slab, Beam, Foundation and Column. Least/Minimum steel percentage is equal to 0.7 percent. Steel Quantity is equal to [0.7/100] x 1 is equal to 0.007 m 3 Steel Weight is equal to 0.007 x 7850 is equal to 54.95 ≊ 55 kg/m 3

Example calculation Estimate the quantity of cement, sand and stone aggregate required for 1 cubic meter of 1:2:4 concrete mix. Ans. Materials required are 7 nos. of 50 kg bag of cement, 0.42 m 3 of sand and 0.83 m 3 of stone aggregate.

The quantity of steel bars, better known as rebar, in a 1 m cubic amount of concrete is dependent upon the use of the concrete. The more steel bars in the concrete the higher the weight rating of ...

We will calculate the required concrete volume for the above beam as, V = L x B x D = 3 x 0.2 x 0.5 = 0.3 m 3. According to the thumb rule, the concrete wastage is 3%, the reinforcement for the above example may be 3% = 0.009 m 3

You May assume 80 kg of steel for one cubic meter ofRCC slab

Heavy industrial = 130 kg/m 3 Commercial = 100 kg/m 3 Institutional = 90 kg/m 3. Residential = 85 kg/m 3. However, while this simplest method to check on the total estimated quantity if reinforcement, same time it is the least accurate and it requires considerable experience to breakdown the tonnage down to Standard Method of Measurement ...

Jun 27, 2018· So by multiplying the quantity of cement with the density of cement, we will the get quantity of cement in terms of kilograms. Unit weight or Density of cement = 1440 kg/cu.m. Quantity of cement in kg(s) = 1440 x 3.90 = 5616 kg. We know that 1 cement bag = 50 kgs

Ca = 1223.8 Kg/cum. The final mix proportions of M-20 grade of concrete become:-Advertisements. ... I want to know how much quantity of steel required for column,slab,footing per cu m.send me the answer approximately. Reply Link. ... aggregate for m-25 concrete for 1 …

.75 kg to 1.1 kg steel required for 1sqft slab. Is This Answer Correct ? 135 Yes : 21 No : How much steel required in 1 square feet slab?.. Answer / ... FOR concrete structure curing is important for hydration process,curing component is good for the concrete if W/C ratio is more than .38 .

so first 10cum converted into CFT that is 353.10(10/0.02832)=353.10 Cft x 7 lbs/Cft =2471.70 then convert in to Kg so =1121.16 Kg is the answer.so in 10cum qty of concrete required 1121 kg steel. Was this answer useful?

Answer / s.nagabhushana rao. Normally steel required for the slab is designed based on the type of slab & the load factors.Normally for thumb rule at site we take as 15 kg / sq mtr.

The bags of cement are assumed to be 25 kg and the largest size aggregate is assumed to be of nominal size 20 mm. Mix: Materials: 0.2 m 3 concrete: 0.5 m 3 concrete: 1 m 3 concrete: A1: cement (no. 25 kg bags) 2.5: 6: 12: sand (volume in m 3) 0.1: 0.25: 0.5: coarse aggregate (volume in m 3) 0.2: 0.5: 1: water (volume in litres) 32: 80: 160: B1:

It all depends on the type and sizes of the steel used. It also depends on the load that the concrete has to take at certain points. 7865kg is the weight of a cubic meter of steel. Typical ...

* then the amount of water (generally between 130 and 150 Litres for 1m3 of concrete) * and lastly, if required, the amount of additives (a few Kilograms for 1m3 of concrete). One cubic metre of concrete weighs 2.5 Tonnes. Typically, 1m3 of concrete is made up of 350Kg of cement, 700Kg of sand, 1,200Kg of chippings and 150 Litres of water.

which size of box use of cement,sand,aggregate to use the m 20 concrete. i know the quantity of material cement 400 kg or 8 beg,662 kg sand and 1200 kg aggregate. i can use only 1 beg cement so pls give me answer . thx in advance . 4 Answers HCC,

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: F-15: so 15 x 25 = 375 kg cement/ cub.meter For 30 mpa we use F-14. 14 x 30 = 420 kg cement/cub.meter Etc. All by WC ratio of 0.5-0.6

Dear Habeeb, It is depend how much MPA for the concrete, higher concrete MPA need high rebar also. As my experience for Fc32 is200 -250 kg/m3. For Fc40 is200 -400 kg/m3, but these are not efficience. Normally the ideal is110-125 kg/m3. I hope this information useful for you. Thanks Andi

Eg:- Load (tensile force) on beam is slightly greater than load on slab so, steel quantity in beam is slightly more than slab. Likewise in every structural elements. Therefore, Slab /lintel——0.7 to 1.0% (55 to 78.5kg)/m^3. Columns_____0.8 to 6.0% (62.80 to 471kg)/m^3. Beam _____1.0 to 2.0% (78.5 to 157kg)/m^3
