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.

How much sand is needed for one cubic feet concrete?
Concrete is a mixture of sand, gravel, cement, and water. Generally, you have 1 part cement, 2 parts sand, and 3 parts gravel. Sand makes up about 1/4 or 1/3 of a cubic foot. At 100 pounds per cu ft that is about 25-35 pounds.
How much sand gravel and cement do you need to make 1 cubic yard of concrete?
500 pounds cement, 1500 pounds sand, 1600 pounds gravel. Mix with 32 gallons water
How much does 1 cubic yard of cement weight?
What is the weight of one cubic yard of cement? If you are asking the weight of 1 cubic yard of CONCRETE it is approximately 2 tons or 4000 pounds per cubic yard when wet.
How many pounds in cement bags?
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.
How much sand is needed for one cubic feet concrete?
Concrete is a mixture of sand, gravel, cement, and water. Generally, you have 1 part cement, 2 parts sand, and 3 parts gravel. Sand makes up about 1/4 or 1/3 of a cubic foot. At 100 pounds per cu ft that is about 25-35 pounds.
How many kilogram of cement are there in 27 cubic feet?
That is approximately 1,841 pounds of concrete.
How much sand gravel and cement do you need to make 1 cubic yard of concrete?
500 pounds cement, 1500 pounds sand, 1600 pounds gravel. Mix with 32 gallons water
How much cement is needed to build a sidewalk that is 132 inches long 24 inches wideand 3 inches think?
Well, you make a sidewalk from concrete, not just cement. Concrete consists of cement, sand, gravel and water. You will need 5.5 cubic feet of concrete. A standard sidewalk grade of concrete would be 1 part cement, 2 parts sand, 3 parts gravel- so the sidewalk needs 0.91 cu ft of cement- about 87 pounds worth- plus sand and gravel. If you want to buy the premixed bags of concrete (like Sacrete), you will need about 17 of the 40 pounds bags. And you did not ask, but 3 inches is kind of skinny- I would go for at least a 4 inch thick sidewalk.
How do you mix 3000 lb concrete?
There is a type of truck called a cement mixer, which carries a large, rotating container in which cement or concrete can be mixed. That's what I would use, if I needed to mix 3000 pounds of concrete. Alternatively, to mix by hand, I would put it in a large container and stir it with a canoe paddle. But that would be very strenuous. Also, it is a lot easier to pour, if it has been mixed in a cement mixer. If you mix it in some other container, pouring it is going to be a major challenge.
Does a 60 pound bag of cement weigh 60 pounds when dried concrete?
No, a 60 pound bag of cement does not weigh the same when it is turned into dried concrete. Once mixed with water and set, the weight of the dried concrete will be slightly more than the original weight of the bag of cement due to the water and other additives in the mixture.
Do you measure a bag of CONCRETE in grams or kilogram?
Concrete is made from cement. This normally comes in 20 kg bags. So the answer is kilograms. A kilogram is roughly 2.2 pounds.
How do you Determine the Specific gravity of cement?
To determine the specific gravity of cement, you typically use a Le Chatelier flask method. This involves measuring the weight of a specific volume of cement and comparing it to the weight of an equal volume of water. The specific gravity is then calculated as the ratio of the weight of cement to the weight of an equal volume of water.
How heavy is a bag of cement?
From the largest manufacturer of backaged Portland Cement, bags come in 92.5 lb bags. To be clear, cement is mixed with sand and often aggregate (pea-gravel up to much larger rocks or other things such as broken out concrete chunks) to make concrete. Portland Cement by itself has no structural integrity when mixed with water. It must be mixed with sand at a minimum to make a hard, useful product (concrete). Concrete comes in bags weighing 50, 60, and 80 pounds here in the US.From the largest manufacturer of backaged Portland Cement, bags come in 92.5 lb bags.
