Traditional concrete walls and columns tend to range from 3 000 to 5 000 psi while 4 000 to 5 000 psi is needed for pavement.
Psi of concrete in 8 ft wall.
For a wall made of concrete the calculation is practically the same.
Block wall thickness blocks filled per cubic yard concrete grout per 100 block concrete grout per 100 square feet wall area.
Any slab exposed to freeze thaw conditions should be a minimum of 4 000 psi.
Concrete mixes are designed to a specified compressive strength expressed as pounds per square inch psi.
6 120 83 yd 3 93 yd 3.
Concrete structures in colder climates require a higher psi in order to withstand more freeze thaw cycles.
Calculate volumes for concrete slabs walls footers columns steps curbs and gutters.
150 at 1 300 at 2 450 at 3 etc.
You can upgrade to 4 000 psi concrete if you desire but i would only do this if it was specified by the structural engineer.
Enter dimensions in us units inches or feet or metric units centimeters or meters of your concrete structure to get the cubic yards value of the amount of concrete you will need to make this structure.
It makes your construction project planning and budgeting more accurate.
This is especially a problem for concrete that might be exposed to freezing and thawing conditions.
Greater psi ratings are useful for retainer walls as they need to hold back the immense weight of soil.
Strength strength is most commonly measured by the designed compressive strength in pounds per square inch psi of a hardened cylinder of concrete.
Concrete has inherent compressive strength resistance to forces pushing on it.
2 x2 tie pattern equal 4 sq.
Height ft x width ft x length ft.
Don t forget that the concrete comes in different strengths depending upon how much cement is added at the ready mix plant.
Per tie x 150 x height of pour pressure per tie.
Our concrete calculator provides you an easy way to calculate concrete volume and estimated cost of concrete slabs footers walls columns steps stairs curbs and gutters in cubic feet cubic yards and cubic meters and inches.
For example to calculate the volume in cubic meters for a wall with a height of 2m width of 20cm and length of 4m you need to multiply 2 x 0 2 x 4 which equals 1 6 m 3 cubic meters.
Concrete pressure compounds with the height of the pour.
Calculate volume of square slab calculator use.
Poured concrete walls are also listed in differing units depending on the contractor.
Concrete wall cost per linear foot per square foot and per cubic yard are the most common units that contractors use.
Concrete for household works such as driveways or floors is typically in the range of 1 800 psi to 4 000 psi for compressive strength.
Suspended slabs beams and girders as often found in bridges require 3 500 to 5 000 psi.
I would use a minimum mix of 3 500 pounds per square inch psi mix.
