How can you calculate the concrete of construction?

To calculate concrete rulesDisplayed along the base × × × thickness number of similar rules, for example ........4 rules 2.4 m length of the show ..... 14:00 ......... height of 0.6 m6 rules girth 1.8 m length of 1.6 m width .... ....... height of 0.5 mThe amount of concrete =2.4 × 2 × 0.6 × 4 = 11.5 cubic meters1.8 × 1.6 × 0.5 × 6 = 8.6 cubic metersConcrete rules total 11.58.6 = 20.1 cubic meters we ask from the factory 21 meters because he will remain in the pump half a meter and Seatonather here and there another part.To calculate concrete AlmidatAlmidat displayed along × × height, for example .......Almidat lengths of 140 meters and its width of 0.3 m and a height of 0.6 m shall be concrete size is 140 × 0.3 × 0.6 = 25.2 cubic meters, we ask 26 cubic metersTo calculate concrete columnsThe number of columns × × column along the column width × height, for example column ........12 length of 0.4 m width and column ......... ........ 0.2 m high and 3.2 m6 columns along ......... 0.5 m width and 0.2 m height ........ 3.2 m4 columns along ......... 0.6 m width and 0.2 m height ........ 3.2 mThe amount of concrete columns =12 × 0.4 × 0.2 × 3.2 = 3.07 cubic m6 × 0.5 × 0.2 × 3.2 = 1.28 cubic m4 × 0.6 × 0.2 × 3.2 = 1.54 cubic mThe total concrete columns = 3.071.281.54 = 5.89 cubic m 6.5 m cubic askTo calculate concrete ceilingThe first way is that the rapid and concrete equivalent to two thirds the size of the roof and the third is the third block, for example ........Ceiling 360 square meters and a thickness of 0.3 m shall be its size = 360 × 0.3 = 108 cubic metersSo the total concrete ceiling = 108 × 2/3 = 72 cubic meters.The second way which calculate the size of the block and equal to the length, block display × × × thickness number then subtract this size from the size of the roof and you get the amount of concrete.In the case of your roof and thickness of 25 cm every 100 meters you need to 17 cubic meters and therefore you need a 41 cubic meters.Come together the way we apply first and second in the concrete ceiling account and see Is it 41 or not ........The first way the size of the roof 240 × 0.25 = 60 cubic metersConcrete amount of two thirds the size = 60 × 2/3 = 40 cubic meters means Hspti true.The second way every flat meters by 6 blocks, and therefore there is a ceiling Block numbering 240 × 6 = 1440 Size 40 × 20 × 17 cm.Block size of 1440 × 0.4 × 0.2 × 0.17 = 19.58 cubic mSo the size of the concrete 60. = 19.58 = 40.5 cubic meters and this is true.To calculate the approximate amounts of iron track of what followsIron rules ......... every cubic m Concrete he have 45 kg of iron.Iron columns ........ every cubic meter concrete obliged 120 kg ironIron Almidat ........ all concrete cubic meters he have 40 kg of ironAlhorda ceiling .... every meter of the flat ceiling he have 30 kg of iron (this in your country, but in my design in Palestine is not more than 20 kgAnd therefore I expect that your roof will need 7.5 tons of iron columns and 800 kg of iron almost 1 ton and your rules and Almidh will take 8.5 tons a total of 17 tons of iron necessary for the completion of the roof Ground
