May 23, 2016 You also have to know the typical energy output from a ton of whatever coal you are using. Taking your figure of 200 kg of coal and 4.7 M BTU output, you would have 23.5 BTU/kg. Covert your BTU figure to Kcal, and plug it into your 770 Kcal per to...
May 09, 2012 Cement manufacturing is highly energy- and emissions-intensive because of the extreme heat required to produce it. Producing a ton of cement requires 4.7 million BTU of energy, equivalent to about 400 pounds of coal, and generates nearly a ton of CO 2. Given its high emissions and critical importance to society, cement is an obvious place to
One cubic yard of concrete converted to ton US (short) equals to 2.03 sh tn. How many short tons US of concrete are in 1 cubic yard? The answer is: The change of 1 cu yd yd3 ( cubic yard ) unit of concrete measure equals = to 2.03 sh tn ( ton US (short) ) as the equivalent measure for the same concrete type.

Jan 24, 2012 Simple calculation. Usually it's 1:4 so for every 4 kg of sand 1 kg of cement. As they called tone bag around (400 kg) you'll need 100 kg cement. So one tone bag of sand four bags of cement. Hopefully this will help mDucanon
Apr 20, 2017 You'll need a bit more than one 1 ton bags of ballast and around 6 bags of cement I reckon. A 1 ton bag is actually around 900Kg ish, so probably 40-45 bags at 25kg each is my guess. 1:4 ratio is quite strong, 1:6 would be fine 12 shovels of ballast to 1/2 bag of cement.
In the step 3 of “How To Calculate Quantities Of Cement, Sand And Aggregate For Nominal Concrete Mix (1:2:4)” you have calculated that: 01 cum of concrete will require Cement required = 1/0.167 = 5.98 Bags ~ 6 Bags Sand required = 115/0.167 = 688 Kgs or 14.98 cft
1970 and 2010, primary physical energy intensity for cement production dropped 1.2% per year from 7.3 MBtu/short ton to 4.5 MBtu/short ton. Carbon dioxide intensity due to fuel consumption and raw material calcination dropped 24%, from 610 lb C/ton of cement (0.31 tC/tonne) to 469 lb C/ton cement
