A concrete mix requires 2 parts sand and 3 parts cement how many pounds of sand are needed for 75 pounds of cement?
You already have the amount of cement you need 75lbs so that is your 3 parts cement. 25 + 25 + 25 =75. Now add the 2 parts sand 25 + 25 = 50lbs. --------------------------------------------------------------------------------------------- Find fractional parts. There is a total of 5 parts. 2/5 = .4 is the fractional part of sand and 3/5= .6 is the fractional part of cement. Then .4 x 75 = 30lb is the sand and .6 x 75 = 45lb is the cement. This gives 75lbs of concrete. If you are asking how much sand to add to 75lbs cement the top answer is correct.

A U.S. bag (or sack) of cement contains 94 lbs. Note this is for cement not premixed concrete where you just add water. The origin of 94 lbs/sack for cement comes from 1 cubic foot of loosly bagged cement weighs approximately 94 lbs; they were originally (and perhaps still) measured out by volume, but for weight calculations, the weight of 94 lbs became standardized.
How do you calculate total cost of 1 cubic meter reinforcement cement concrete of heavy foundation work?
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.
