Formula for calculating compressive strength of cylindrical body of concrete?

∙ 13y ago
If the concrete sample has been tested in a uniaxial compressive test machine (which would be the normal destructive method of testing a cylindrical sample), then you would use the failure load divided by the cross sectional area of the cylinder to find the strength of the material.
Failure Stress = Uniaxial Compressive Strength = Force / Area
It should also be noted that concrete strength is more normally found by measuring "cube strength", that is where the concrete is pored into cube shaped moulds of 100 mm x 100 mm x 100 mm and is then allowed to cure for a period of time (typically 28 days). The concrete cube is then tested in a uniaxial test rig. The formula for calculating the strength is the same, however the major difference is in the preparation of the sample as described above.

What is the compressive strength of M40 concrete?
40 MPa
What do you mean by M20 concrete?
In this M refer to Maximum compressive strength and 20 refer that concrete that with stand upto 20KN compressive strength.
What is the difference between fc and fcu in concrete?
f ′c: concrete compressive strength at 28 days (compression is negative) fcu: concrete crushing strength (compression is negative)
Is the characteristic strength of a concrete the same as the compressive strength?
Yes, the characterisrtic strength of a concrete is the same as the compressive strength
What is C25 concrete?
C25 concrete is a concrete having compressive strength of 25MPa when tested at the 28th day after casting. The specimen can be cube(150x150x150) or cylindrical(125mm by 250mm high). The cube strength has 0.8 times that of cylindrical specimen due to shape factor.

What is an example of compressive strength?
Concrete's capacity to withstand compressive forces is an illustration of compressive strength. A concrete structure, like a column or a beam, experiences pressure when it is subjected to a load. Concrete's capacity to withstand this pressure without breaking or deforming is measured by its compressive strength. For instance, structural concrete must have a compressive strength of at least 25 megapascals (MPa), which indicates that it can withstand significant compression without breaking. In determining the structural integrity and durability of various building materials, compressive strength is a crucial factor.
