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 many kilogram of cement are there in 27 cubic feet?

That is approximately 1,841 pounds of concrete.


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 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 many pounds of concrete are needed per fence post?

The amount of concrete needed per fence post typically ranges from 50 to 80 pounds, depending on the size and depth of the hole.


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 much cement is in 4500 psi concrete?

Well, friend, 4500 psi concrete typically contains about 564 pounds of cement per cubic yard. It's like adding just the right amount of color to your painting to achieve the perfect shade. Just the right balance of cement helps create strong and durable concrete that can withstand the test of time.


How do you Determine the Specific gravity of cement?

Cement is usually purchased as a powdery substance that is mixed with sand, aggregate, gravel and water to form concrete. Since the cement itself is usually a powder, it is hard to measure a standard value for it's specific gravity. And since cement is usually not used by itself, knowing it's specific gravity is not particularly useful. A more useful question is "What is the typical density of concrete?" A rule of thumb answer is that normal cured concrete has a density of about 150 pounds per cubic foot. This includes the weight of the cement, sand, aggregate, and that part of the water that chemcially binds with the cement to form the concrete. Since water weighs about 62.4 pounds per cubic feet, concrete is about 2.4 times as heavy. Thus the specific gravity of concrete is about 2.4. If you took cement and mixed it with water, you would eventually have a hard lump of useless cement and it would also have a specific gravity of between 2 and 2.4. Ash Grove Cement from the Foreman, AR Facility normally has a specific gravity of 3.15. Depending on the source of the cement, the specific gravity may vary, but typically it will be close to this figure. Knowing the specific gravity of cement is critical when developing a mix design for concrete, because if one does not know the specific gravities of the raw materials, it is not possible to figure the proportions needed to give you the appropriate yield for a cubic yard of concrete.


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.
