120 kGS upto 200 kgs will be use and it may varies depends on structure and design.
Approximately 2.0 tonnes/m3.
Concrete weighs about 150 pounds per cubic foot. Can't do the math but that is about 4500 pounds.
4050lbs. A cubic foot of concrete weighs 150lbs. There are 27 cubic feet in one cubic yard. ------------------------------------------------------------------ Fresh concrete can weight about 3700 lbs for every cubic yard. The density will also determine how much is its weight. assuming its weight to be around 150 lbs for per cubic feet. This would make it around 4000 lbs which could come to 2 tons. ---------------------------------------------------------------------- Calculating the weight of reinforced concrete could be a bit more difficult since this type come with steel bars. On an average, we could assume 500 lbs for steel density per cubic feet which is almost 3 times more than cement. So with this calculation, we can assume the weight of reinforced concrete to be around 4000 lbs.
Prestressed concete made using high tensile wires which is stressed (as per the design load) before concreting, and post tensioned concrete made of Strands covered with duct, in this, wires/strnads are stressed after concreting then the ducts are grouted using cement slurry..
$1000 depending on their expertise
well , reinforcement steel required for slab is nearly 0.7 to 0.8% of the volume of concrete so if concrete is 1 cum then steel will be 1*0.7/100 =0.007 but density of steel is 7850 kg/ cum so 0.007*7850=54.95 say 55 kg per cum so steel required to reinforce 1 cum concrete for slab is approximately 55 kgs.
Weight of concrete is 155 lbs/cft or 70.308 kg/cum
because concrete is unpredictable than steel
For nominal Mix Cement consumption for M25 will be 570 kg per cum. and for Design Mix it can be optimised to 510 kg per cum.
As per the civil engineering thumb rule, weight of steel for one cubic meter of concrete is 100kgs to 130 kgs for normal structures
8.4 beg (per beg 50Kg.) (420kg cement)
Yes you can get Pregnant from per-cum but change are much less then you full time cuming in here which is also known as the big bang

how much does concrete cost per square foot
Materials on a steel pole barn usually run along the price range of $5.00 per square foot without concrete. Since steel poles eventually rot, you will have to spend some money to get them replaced regularly. If you do consider concrete, the prices can range from $9.00 to $33.00 per square foot. Apply this to the dimensions of your barn and you can estimate the cost.
well i dont know where do you want to construct the slab but for your better understanding i am giving you market rate of pune region first the costing depends upon the raw material & labour cost in your local area. well assume the rates as cement :- 235 Rs per Bag river sand :- 5200 per brass i.e. 5200/2.83 =1837.45 cum metal:- 2200 per brass say777.38 cum reinforced steel 35.5 Rs per kg so consider M15 cc with hand mixing & unit 1 cum( your actual qty is 9*7*0.1=6.3cum) cement 6.28 bags*235=1475.8 River sand 0.44 cum*1837.45=808.47 metal 0.88cum*777.38=684.09 steel 55 kg *35.5=1952.5 so total material cost is 1475.8+808.47+684.09+1952.5=4920.86Rs labour for concreting will be 250 rs per cum shuttering cost will go around Rs 1500 per cum water & misc charges will be 75 Rs total material , labour cost is 4920.86+250+1500=6670.86 add 10% contractor profit say 667.086 so total cost to lay 1cum concrete of M15 in pune region of Maharashtra will be 7737say7740 Rs per Cum & your requirement is 9*7*0.1=6.3 cum so you will require 6.3*7740=48762 Rs approx for slab in pune local market please tally the rates according to your local area rates to find out cost in your local area . hope the answer will satisfy your needs.
Considering the different applications and methods of concrete construction, you really can't calculate it that way.
