Concrete Cylinder Compression Test (ASTM C39)

This video shows how the compression strength of concrete (f'c) is measured using a standard cylinder (per ASTM C39).

Thank you to my dad for creating the music.

Very useful.
I just wished you had the lab apparatus detailed in the description box .
And the procedures ( trying to do a lab report) .
Ahah

so i just poured the 60th floor of a skyscraper.. and the 4th floor cylinders were tested and failed at 250 PSI... what do I do? add a zero to the number or should I let the consultants know?

[truthbetold]

what concrete ratio did u use for the test?

What is the difference if I'll using sulfer for caping cylinder ?!

thank you very much. I needed this for my university project

I did 1000's of these, but just went by the machine #'s. No measuring, or cutting.

Hello po engr. Mga ilang tonnes po kaya ang kayang ipatong (upright)sa culvert na may sukat H 1.5m W 1m thickness 10cm..

what water cement ratio did you use for the specimen?

the rupture of the test piece is not correct, if you plan (by rectification) the two loading faces, the test result is more reliable and the mode of rupture is correct.

What does the symbol Ac in the equation represent please ?

[CarbonTaxLOL]

Why does a larger sample diameter return lower results of compressive strength?

what is the point of this video without talking....this isnt how the labs take place with banjos playing in the background
