You'll need 60 60-lb bags of concrete to construct a yard if you're using 60-lb bags. If you're using 80-pound bags of concrete, 45 bags will be required to construct a yard.
Concrete is heavy so it's important to use a proper scale to measure the amount you need for your project. Concrete is heavy when wet but once it hardens it becomes very dense. For example, one cubic foot of dry concrete has a density of 3,000 pounds per cubic foot while one cubic foot of liquid concrete has a density of approximately 7,000 pounds per cubic foot.
The weight of the concrete and any additives such as sand or gravel (if used) should be recorded before mixing them with water. Calculate the amount of water needed by multiplying the total weight by 0.45 if you're using 80-pound bags instead of 60-pound bags. Additives will change depending on what type of mix you create but for general purposes, 2% of the total weight is a good start.
Now you can calculate how much water you'll need for your project. Use this number plus the ratio of water to additive found in your calculation method's instructions to determine how much water to buy. Most calculators available today can easily factor in dollar amounts so there's no need to do any rounding up or down.
As we know, the volume of a 60 lb bag of concrete is around 0.017 cubic yards, and one cubic yard of concrete weighs approximately 3600 lb, thus the number of bags of 60 lb concrete in one cubic yard is 3600/60=60, indicating that there are 60 bags of 60 lb concrete in one cubic yard.
A yard is the amount of space you can fit a standard length of fencing into. One yard is equal to about 9 feet 5 inches. So if you have a lot of concrete that needs to be poured, the number of bags will depend on the size of the pour. For example, if the pour is 7 feet by 10 feet, then it would take seven 20-lb bags to fill the car. As far as weight is concerned, 1 cubic yard weighs about 200 lbs. Thus, seven such pours in one day could weigh 7000 lbs!
Concrete is heavy. A ton of concrete weighs about 2200 lbs. So for your average size house, this would mean needing to transport a couple of loads of concrete a month just to keep up with what gets poured at any given time. That's a lot of concrete!
The best way to transport concrete is in open trailers or flatbed trucks. This allows for easy access to all parts of the truck bed while keeping out the weather. Avoid transporting concrete during hot summer days since it will increase the temperature of the material which could affect its quality and cost.
(A cubic yard of concrete requires around forty 80-pound bags of prepared components.) Alternatively, 1 cubic meter of concrete requires around 7.15 bags of Portland cement. There will be 48 cubic meters of sand and.51 cubic meters of gravel. That's about 0.5 cubic yards each.
The total weight of the cement required is 454 pounds for a single cubic yard. The average price of Portland cement in the United States is $150 per ton. That makes the cost of one cubic yard of concrete $220.
Concrete is the most common building material used by mankind. Concrete is a mixture of water and cement that sets into an insoluble solid when mixed together and allowed to cure. Cement is the key ingredient that allows concrete to become water-resistant once hardened. Regular concrete can withstand freezing and thawing cycles without deteriorating. High-strength concrete can resist pressure, heat, and chemical attacks better than regular concrete.
One cubic yard of concrete covers an area of approximately 9 x 12 feet or 2.5 x 3 m. It can be cut into smaller pieces if need be. However, not all concrete projects require a whole yard of concrete. A single cubic foot of concrete has a density of about 22 pounds per cubic foot. This means that one cubic foot of concrete will fill a space about one-quarter of its size.
A bag of pre-mixed cement, sand, and gravel (CONCRETE) weighing 80 pounds contains 0.6 cubic feet. A cubic yard has a volume of 27 cubic feet. As a consequence, 27/0.6 = 45 80# bags are produced.
The number of bags needed to fill a truck is easily found by multiplying the load capacity of the truck by the total weight of the concrete required. In this case, it's 90 tons or 9000 lbs. Since each bag weighs 80 lbs, the number of bags required is 9000 divided by 80, which comes out to 11 50-lb bags.
The average person can lift up to 100 lbs so if you have a friend who can help out then this job can be done in a day instead of making several trips to and from the dumpster.
However, if you plan to do the lifting yourself then you will need to be able to lift at least 100 lbs. This means that you will need to find people who can help out with this project too. It's best to start off with friends or family members who are available to help out. If you have enough people working on the project then it can be done in a single day.
In conclusion, the number of bags required for this project is 11 50-lb bags.
