7 Parts sand to 1 Part portland cement
Yes, there are parts of the Atacama that are covered in sand. See the image above.

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.
it is typically 5 parts lime, 3 parts sand, 1 part cement, but varies depending on use and situation
