The answer will depend on the size of the concrete block!
Concrete, Mortar, Brick, Block, Re bar for support
Yes. Ron Lacher Pool Engineering in southern California probably has an engineering detail showing how to build it.
To calculate the number of concrete blocks needed for a building, you first need to determine the area of one block and then divide the total building area by the block area. Concrete block sizes vary, so you will need to know the dimensions of the block you plan to use. Once you have that information, divide the total building area (25x30) by the block area to find the number of blocks needed.
That's sort of a strange question. A concrete slab is a horizontal surface -- it's meant to be a surface you stand on or build things on. Concrete blocks are usually used for vertical surfaces -- walls. I believe that poured concrete walls are more expensive than concrete block walls. You wouldn't use concrete blocks as a substitute for a concrete slab.
They used concrete.
To create a cinder block mold for your DIY project, you can use plywood to build a rectangular frame that is the size of a cinder block. Make sure the frame is sturdy and has no gaps. Then, line the inside of the frame with a release agent to prevent the concrete from sticking. Pour the concrete mixture into the frame and let it cure before removing the mold.
Use concrete to build a nice archway.
First, convert the dimensions of the building from feet to inches: 6 ft = 72 inches, 6 ft = 72 inches, and 7 ft = 84 inches. The volume of the building is 72 x 72 x 84 = 432,432 cubic inches. The volume of one 8x8x16 block is 8 x 8 x 16 = 1,024 cubic inches. Therefore, the number of blocks needed is 432,432 / 1,024 ≈ 422 blocks.
starting on the low ground side, dig a trench the full length and after pouring the concrete to almost ground level, start with your first block and as it heads into the trench, come back one half of a block and again pour the concrete to near ground level and lay another block and continue doing this until you reach the end. You will find that on your first course you will have only one block on one end and several on the other depending on how much out of level the ground may be. Hope this helps.
The volume of concrete used to build the Millau bridge is 85,000 m3 (cubic meters). The weight of this volume of concrete is 206,000 metric tons.
