Multiply the length (10 ft.) by the width (10 ft.) by the depth (.35 ft., or 4 in.) and divide it by 27 (the number of cubic feet in a cubic yard). You get 1.3 cu. yds. Then add 10 percent to allow for spillage and slab depth variations to help determine the concrete cost per yard.

We''ve had two tests on a job site performed by concrete engineers. Both of them debunked this myth that dry pour is not structural. Both of them also raise concerns that after a year or two to exposed weather the concrete will just start to diminish because of improper water to cement ratios. Reply reply. WhoKnows78998.

Step 3: Mixing in Water. The amount of water added to concrete is called the water/cement ratio. Though adding more water to the concrete will make it easier to mix, pour, and work with, it actually lowers the concrete strength of the concrete when cured. This is because the hydration creates interlocking crystals and the more water in the mix
