How can I properly pour dry concrete over gravel to ensure a strong and stable foundation?

To properly pour dry concrete over gravel for a strong and stable foundation, follow these steps: Prepare the gravel base by leveling and compacting it. Use a wooden or metal form to contain the concrete and keep it in place. Pour the dry concrete mix evenly over the gravel base. Use a rake or shovel to spread and level the concrete mix. Add water gradually and mix the concrete thoroughly until it reaches the desired consistency. Compact the concrete using a tamper or vibrating plate to remove air pockets and ensure a solid foundation. Allow the concrete to cure and set according to the manufacturer's instructions before proceeding with further construction.

How many bags of cement sand and gravel to make 1 square yard of concrete?

Figure about 1/2 cubic foot per 60 lb bag. The basic formula is to use equal amounts of cement, sand, and gravel. There are 27 cubic yards per cubic foot. It depends upon how thick you are planning to pour the concrete. For one foot thick, you would need 9 cubic feet of concrete. For 6" thick, you would need 4 1/2 cubic feet. I'll give you the answers for 1 ft thick and for 6" thick. For 1 foot thick, you need 9 cubic feet at 1/2 cubic foot per 60 lb bag equals 18-60 lb bags. That's six 60 lb bags of concrete, plus six 60 lb bags of sand, plus 360 lbs of gravel. For 6 inches thick, divide each of these by 2 to give 3-60 lb bags of concrete, 3-60 lb bags of sand, plus 180 lbs of gravel.
