How many cubic meter per 1 bag cement 40 kg?

One cubic meter of concrete is equal to 1.308 cubic yards of concrete. If there are 5 1/2 bags of cement in 1 cubic yard of concrete, there would be 7.2 bags in 1 cubic meter of concrete. These are the 94 pound bags of portland cement or roughly 40kg bags so figure 8 bags total. Some will be left over

70 cubic mitre of concrete how many cubic mitre of sand gravel and cement to make concrete of grade 15?

I cant accuratly help you with the cement content but you need about 1 ton of sand and 1 ton of stone for every cubic meter of concrete. The cement content would depend on what you are using the concrete for. At 15 newtons of strength you would ( and this is just an educated guess) need about 95kg of OPC cement, 85kg of GGBS slag, 1.5lt of WRA (water reducing agent) and about 70lt of water to gain a 50mm slump per cubic meter. If I were you I would get it ready mixed. 70 Cube is a LOT of cocrete. Ready mixed 15 Newton concrete is about £75 inc vat per meter delivered. Regards Colin, a Tarmac concrete batcher.

How much does 1 cubic yard of concrete weigh?

This can vary do to the mixture of sand, stone, cement... but an approximate average would be 3000 lbs

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 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 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 cement is needed for a 1000 square 5 inch deep area?

Assuming you mean 1,000 square feet, the math works like this. Concrete is typically measured in cubic yards. A cubic yard is 3ft X 3ft x 3ft OR 27 cubic feet. Your volume of concrete would be 1000 x (5/12) = 416.6 cu.ft. / 27 cuft = 15.4 yards of concrete. Be sure to account for waste, slope (which may thicken your slab), etc.

Cement required for m20?

For M20 grade concrete, the mix proportion is 1:1.5:3 (cement:sand:coarse aggregates). If we consider a volume of 1 cubic meter, approximately 320 kg of cement would be needed.

How much does 9 cubic yards of cement weigh?

Answer #1:9 cubic yards cement weight nearly 1260 lbs=============================Answer #2:Answer #1 is a very intriguing one. It says that 9 cubic yards (9 x 27 cubic feet)of cement weighs nearly 1,260 pounds. If so, then each cubic foot would weighnearly 5.2 pounds, which corresponds to nearly 8.3% of the density of water.So cement would float quite high in water. Mysteriously, it doesn't.I found one online conversion reference that says that1 cubic foot of Portland cement weighs 94.02 pounds.(94.02 pounds/cubic foot) x (9 cubic yards) x (27 cubic foot/cubic yard) = 22,847 pounds(rounded)Somehow, that sounds more like it.Also, if the question actually meant 'concrete, limestone with Portland cement"instead of 'cement', then the weight is nearly 60% greater than that.

How much concrete can be made using one bag of cement?

Concrete strength is measured by "bag mix", meaning that the bag mix answers the question, how many bags of cement per yard of concrete. If you're looking for a "6 bag" mix, that means 6 bags of cement per yard of concrete. A "bag" of cement is 1 cubic foot. A yard of concrete is 27 cubic feet (3 X 3 X 3 = 27). If you want to make a "6 bag mix" of concrete, using 1 bag of cement, you would make 1/6 yard concrete with 1 bag of cement. If you would be content with a "5 bag mix", you could make 1/5 yard. Concrete is often defined as ratios of cement,sand,aggregate such as: 1:2:3 which is a very common mix. For a 1:2:3 mix you would need 1/6th of the volume to be cement. The dry ingredients are generally 1.6 x finished concrete volume. Therefore dry volumen for 1 cubic yard = 1.6 cu yards = 43.2 cu ft. 1/6 x 43.2 = 7.2cu ft. Therefore, if one bag is 1 cu ft we need 7.2 bags for a healthy 1:2:3 mix. A '6 bag mix' or a '5 bag mix' are a bit short on cement.

How many yards of cement do you need for a 20.5 x 21 x 4 slab?

About .0369 cubic yards. 20.5"x21"x4"=1722 cubic inches 1 Cubic yard of concrete is 27 cubic feet (9'x9'x9') 1 cubic foot of concrete is 1728 cubic inches (12"x12"x12") 1 cubic yard = 27 x 1728 = 46656 cubic inches 1722/46656 is approximately .0369 This would be a little less than two 80# bags of concrete mix

What is the weight of 1 yard of Cement?

This question has been answered already. The answer given was:Depending on the relative proportions of water, sand, stone, and cement, the weight per cubic yard can vary from less than 2000 lbs to nearly 3500 lbs; I would estimate most commercially (truck) delivered concrete would run close to 3300 lbs per cubic yard - remember there are 27 cubic feet in a cubic yard!
