Edits to Concrete slump test
This refers to your edits here.. The link (called diff) demonstrates what you have removed and added. Your edit goes as follows:

''First of all we have to prepare a mixture a mixture of concrete having ratio of: 1:2:4. That is one part of cement, two parts sand, and four parts of crush. Determine the volume of the cone in cubic feet. It is determined by taking the mean diameter of the cone and with it finding the area of the cross section of cone. Then multiplying it with the height of the cone which is 1 foot, will give the volume of the cone. This is the volume of concrete which have to be prepared so that the cone is fully compacted. Then determine the total weight of the concrete, as the specific weight of concrete is 150 lb/ft3. Determine the weight of cement by multiplying the weight of concrete by 1/7, as cement is one part out of total 7 parts. Then determine the weight of sand by multiplying the weight of concrete by 2/7, as sand is two parts out of total 7 parts. Then determine the weight of crush by multiplying the weight of concrete by 4/7, as crush is four parts out of total 7 parts. After calculation of dry ingredients, calculate the amount of water as is given in the ASTM Standard water-cement ratio. [2] For 1:2:4 mixture the water-cement ratio is 0.6, so for weight of water to be added, multiply this ratio with weight of cement. After calculation of weights make a homogeneous mixture of dry ingredients, and then add water carefully to make a paste. Then take the slump-test apparatus and clean it from inside also apply oil to it and to the bottom surface. Then place it on the smooth metallic surface, and fix it firmly. Then put one third of the concrete in the cone and press it with the help of a 5/8 inch, round-ended, tampering rod. It should be tampered 25 times. Then add the second one-third potion of concrete, and also tamper it 25 times with the help of tampering rod. At last add the remaining one-third portion, and also tamper it 25 times. For the upper surface to be smooth work it with float, so that during measurement of slump it is easy to take correct readings. Immediately after filling the cone is slowly lifted, and the unsupported concrete will now slump-hence the name of the test. “The decrease in the height of the centre of the slumped concrete is called slump”.''
