Considering the different applications and methods of concrete construction, you really can't calculate it that way.
100 kgs of tor steel
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.
The mass of a cubic metre of concrete is 2250-2400 kilograms.
.029 cubic yards of concrete weighs aproximately 93.96lbs
You calculate the total cost of 1 cubic meter reinforcement cement for heavy foundation work by adding all of the costs. Essentially you would have to figure out the total of pounds of concrete for 1 cubic meter multiply that by the cost per pound and then add in the cost of labor it takes to pour 1 cubic meter.
One cubic yard every 4.5 linear feet
yes
How thick? Gotta have thickness to calculate cubic yards.
Length X width X Depth (measured in feet) that gives you the total CUBIC feet of concrete you need. BUT Concrete is delivered by the CUBIC YARD so divide your answer by 27 to convert to cubic yards....There ya go
Considering the different applications and methods of concrete construction, you really can't calculate it that way.
Length in ft x Width in ft. x depth in ft. = Cubic feet, divide by 27 to get yards of concrete needed.
Length x width x thickness or depth. Starting with inches, you will come up with total cubic inches using that formula. Divide that number by 1728 to get cubic feet. divide that quotient by 27 to get cubic yards. Concrete is usually sold by cubic yard.
it would depend entirely on the rebar design.....
Oops . . . please repost your question and include the depth of the concrete. You have to have all 3 dimensions in order to calculate volume (Cubic Yards of concrete).
1.75 tonnes 1,750 kg of ballast is one cubic metre, if its concrete then you'd need to add 300kg of cement to mix this to the right ratio for a foundation.
