Psi Pressure Of Concrete Per Foot In 8 Ft Wall

An 8 wall 8 high contains 5 33 cf of concrete per lineal foot of wall whereas an 80 wall 8 high contains 53 33 cf per lf.

Psi pressure of concrete per foot in 8 ft wall.

Per tie x 150 x height of pour pressure per tie. Concrete lateral pressure for walls with placement rate of greater than 2 1 m h and placement height exceeds 4 2 m and for all walls with placement rate of 2 1 to. Set project zip code enter the zip code for the location where labor is hired and materials purchased. This is the base load bearing strength of your concrete.

This is the standard psi of a common mix. Minimum wall thickness 2500 psi concrete wall 8 0 high with 7 4 of backfill 8 inches. 150 at 1 300 at 2 450 at 3 etc. X 150 x 6 height of pour equals 3600.

To estimate costs for your project. Concrete pressure compounds with the height of the pour. Frederick landscaping quotes the concrete wall cost per linear foot at 30 to 40 as a ballpark estimate and the price would depend on several factors such the size of the project location design etc. To compute the full fluid pressure multiply the concrete height by the unit weight of the fresh concrete 150 pounds per cubic foot pcf for standard weight concrete as shown in example 1.

Engineering required wall 10 0 high with 9 4 of backfill 10 inches. Q 5000 concrete mix consists of a commercial grade blend of portland cement sand gravel. If you are doing a smaller home project with no special accelerants added to your mix your load bearing strength per concrete yard will be 3 000 psi. Write this number down.

Concrete lateral pressure for walls with placement rate smaller than 2 1 m h and placement height is no greater than 4 2 m. This note reflects the specific mix you will order throughout your project. Actual costs will depend on job size conditions and options. For a basic project in zip code 47474 with 500 square feet the cost to pressure wash concrete starts at 0 33 0 41 per square foot.

Concrete mixes are designed to a specified compressive strength expressed as pounds per square inch psi. This concrete mix is designed for applications requiring high early strength and rapid strength gains. I try to stay away from concrete but it appears that the form strength required for an 80 wall as compared to an 8 wall differs by a factor of 10. Concrete strength concrete has inherent compressive strength resistance to forces pushing on it.

5000 high early strength concrete mix has a walk on time of 10 hours to 12 hours. 12 inches wall 9 0 high with 8 4 of backfill 10 inches. 2 x2 tie pattern equal 4 sq.
