1.373 x 10 x 10 = 137.3 Kn. So rate of loading will be = 137.3 / 60 = 2.88 Kn/Sec. Same way you can calculate rate of loading for each cube size you test at your laboratory. Kindly note above calculation are done considering your cube testing machine applies load in Kn, if your machine applies load in Kg or Mt kindly change the load on cube ...
So, 100mmx100mmx100mm concrete cubes are used in place of 150mmx150mmx150mm cubes to raise the used stress to crush the concrete cubes. For normal concrete strength, the cube size of 150mmx150mmx150mm is already sufficient for the crushing strength of the machine. Cube Test: Instrument And Material.

we can quickly calculate the weight of most steel sections, by multiplying the actual thickness times 40 psf times the area of each plate that makes up the cross section. • If a 1" plate = 40psf, then ¾" = 30psf, ½" = 20psf, ¼" = 10psf, and so on. Re-do Example S3 Steel Column by Area Method 2" Steel = …
To calculate how much concrete you need, factor in the depth of the concrete. A standard depth is 3 to 4 inches. Multiply this depth times your total square footage. This will give you the cubic feet and how much concrete you will need. It is a good idea to add about 5 percent to this number so you have a little extra.
Quantity – Measurements can frequently be a little off, so we highly recommend ordering a little extra, because coming up short can be a disaster. A good rule of thumb is take your calculation and add 4% to 10% to the total to account for waste, spillage, over-excavation, settlement, spreading of forms, loss of entrained air or any other changes in volume.

To do this calculation, add the sum of ratio 1+2+4=7. Calculate the cubic volume of concrete for foundation. Going by the previous article the total lenght of trench was taken as 65.6m. Height of concrete beam is 1.1m or 1100m from image 2. And width is 0.225m or 225mm. therefore total volume of concrete beams =65.6m x 1.1 x 0.225 =16.236.
