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.

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 60 pound sack make a 1 yard of concrete?
To determine how many 60-pound sacks of concrete mix are needed for one cubic yard, you need to know that one cubic yard of concrete weighs approximately 4,000 pounds. Dividing 4,000 pounds by 60 pounds per sack means you would need about 67 sacks of 60-pound concrete mix to make one yard of concrete.
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 Much water is required for 124 concrete?
The amount of water required for 124 concrete (which refers to a specific mix design typically having a cement content of 124 pounds per cubic yard) generally follows a water-cement ratio. A common ratio is around 0.4 to 0.6, meaning for every 100 pounds of cement, 40 to 60 pounds of water are needed. Therefore, for 124 pounds of cement, approximately 50 to 75 pounds (or about 6 to 9 gallons) of water would be required, depending on the desired workability and strength of the concrete. Always refer to specific mix design guidelines for precise requirements.
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 many 94 pound bags of Portland cement needed for a yard of sand?
To find out how many 94-pound bags of Portland cement are needed for a yard of sand, you typically use a 1:2:3 mix ratio (cement, sand, gravel) for concrete. Since a yard of sand weighs about 1,600 pounds, you'll need approximately 533 pounds of cement for that mix. Given that each bag of Portland cement weighs 94 pounds, you would need about 6 bags (533 ÷ 94 ≈ 5.67). Therefore, you would need 6 bags of Portland cement for a yard of sand.
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 much water 80 lb of concrete mix?
To determine the amount of water needed for 80 pounds of concrete mix, you typically use a water-to-cement ratio. A common ratio is 0.5, meaning for every 100 pounds of concrete mix, you would use about 50 pounds (or approximately 6 gallons) of water. For 80 pounds of concrete mix, you would need around 4 pounds of water, or about 0.5 gallons. However, it's essential to check the specific instructions on the concrete mix packaging, as different mixes may have varying requirements.
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.
How many sacks of cement makes 3000 psi?
The number of sacks of cement needed to achieve 3000 psi concrete can vary based on the mix design, but a typical guideline is using one sack (94 pounds) of cement per cubic yard of concrete. For a standard 3000 psi mix, you might use around 5 to 6 sacks of cement per cubic yard, depending on the aggregate size and water-cement ratio. It's crucial to follow specific mix designs for accurate results. Always consult a concrete mix design guide or an engineer for precise formulations.
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.
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.
