This all depends on the mix you want. I assume you mean cement when you mention the 80lb bag of concrete. I have pushed concrete in my day... Bag cement mix is the same as concrete. Don't be funny. How many 80 pound bags will make 1 yard of concrete? I want a definitive answer this time.
Usually concrete mix comes in 40, 60 or 80 pound bags.
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.
Typically, a 90 lb bag of concrete mix would require around 1.8 lbs of lime if using a 2:1 ratio of sand to cement. However, it's essential to follow the manufacturer's instructions on the concrete mix bag for the correct proportions for your specific project.
The answer is, remarkably, 6. Answer: "6 sack" or "6 bag mix" has six bags of cement per cubic yard of concrete mix. Since each sack/bag contains 94 lbs of dry cement, this equals 564 lbs of cement per cubic yard of concrete.
To make concrete from scratch, mix cement, sand, and gravel in specific proportions with water. The mixture should be thoroughly combined and poured into molds to set and harden.
it takes 45 Bags of 80# mix to make a cubic yard
i wouldn't think so! this is a 55lb. bag of concrete. water weighs 8lbs. per gallon. so you would need to figure out how many gallons of water you are going to use. should be some type of guide line on bag. but remember some of that water will evaporate. so an exact weight would be hard to figure, until the concrete was cured and actually weighted.
A 60-pound bag of concrete mix typically yields about 0.45 cubic feet of concrete. To convert this to square feet, you need to know the thickness of the slab you plan to pour. For example, if you're pouring a 4-inch thick slab, the 60-pound bag would cover approximately 13.5 square feet.
Yes, you can buy concrete mix in a premixed bag that will turn white when mixed with water. These types of mixes are typically referred to as white cement or white concrete mixes, which contain white aggregates or additives to achieve the desired color. Just follow the manufacturer's instructions for mixing and placing the concrete to ensure the best results.
To properly mix and pour concrete for a durable and long-lasting project, follow these tips: Use the correct ratio of water to concrete mix as per the instructions on the bag. Mix the concrete thoroughly to ensure uniform consistency. Pour the concrete evenly and avoid overworking it to prevent air pockets. Use a trowel to smooth the surface and remove any excess water. Allow the concrete to cure properly by keeping it moist and protected from extreme temperatures.
To use concrete for casting sculptures, you will need to create a mold of the desired sculpture, mix concrete with water to form a workable consistency, pour the concrete into the mold, and allow it to cure and harden. Once the concrete has set, you can remove the mold to reveal the finished sculpture.
