To calculate the amount of concrete needed for a 12x12x4 slab, first convert the dimensions to feet: 12 feet by 12 feet by 4 inches (which is 1/3 foot). The volume in cubic feet is 12 x 12 x (1/3) = 48 cubic feet. Since concrete is typically sold by the cubic yard, divide the volume by 27 (since there are 27 cubic feet in a cubic yard): 48 ÷ 27 ≈ 1.78 cubic yards of concrete is required.

If it is 4 inches deep/thick, 2 cubic yards. If it is 6 inches deep/thick, 3 cubic yards.
To calculate the amount of concrete needed for a 9' x 9' x 4' slab, first determine the volume in cubic feet by multiplying the dimensions: 9 x 9 x 4 = 324 cubic feet. Since concrete is typically sold by the cubic yard, convert cubic feet to cubic yards by dividing by 27 (there are 27 cubic feet in a cubic yard). Therefore, you would need approximately 12 cubic yards of concrete for the slab.
You will need a minimum of 39.51 Cubic Yards.

The weight a concrete slab can support depends on its design, reinforcement, and the load applied to it. However, a standard concrete slab of 100 mm (10 cm) thickness, made with normal concrete, weighs approximately 2,400 kg per cubic meter. Therefore, a square meter of this slab would weigh about 240 kg. The actual load-bearing capacity will vary based on factors such as the type of load (static or dynamic) and safety factors applied in structural design.

Fixing a sinking concrete slab on your own using a DIY approach involves lifting the slab back into place. One common method is using a process called slabjacking, where you inject a mixture of materials under the slab to raise it. You can also use polyurethane foam injections or concrete leveling products. It's important to carefully follow instructions and take safety precautions when attempting this repair.

A conventional slab will have two bars side by side near the top and bottom of each beam and a 16" grid across the entire top of the slab. Can't help you with a post tention... they are inventing new ways to take steel out of them every day.
Depends on size and thickness. You take length x Width x Thickness= Then Divide by 27. That will give you How many yards of concrete you need. Then you need to call your local concrete company and get a price per yard. Multiply your yards with price and the you have your price Just for your concrete. Now as far as having somebody to the whole process for you i would call around and get as many estimates as possible to compare prices.
5 yds - One yard of concrete will cover approximately 81 square feet 4" deep.
12-ft x 12-ft x 2-in = 24 cubic feet = 8/9 of 1 cubic yard
