Brazilian Test - Tensile Failure of Concrete in Slow Motion

This film shows the Brazilian test, which is designed to measure the tensile strength of concrete. For more detailed information on this test, including a downloadable data sheet, see our website at:
www.expeditionw...
Tests such as this one are the standard way of measuring the tensile strength of concrete. This test shows that:
- concrete is brittle in tension
- concrete has a low tensile strength compared to its compressive strength
- application of a compressive force can cause cracks to open up in a perpendicular direction
At the end of the video a graph of vertical load versus vertical deflection shows the point at which brittle failure occurs.

This is an indirect tensile test guys, not a compression test

[@moniszaki9523]

This is the tensile strength test also known as split cylinder test. The tensile test for concrete is not possible so this is an indirect approach to it. It is not the compression test in which the cylinder is placed vertically in a CTM or UTM.

Very helpful....these explain the concept very clearly....thank you

How to get rock samples for testing

[@manishpaswan5075]

Please upload compressive failure of concrete

[@rehatami]

why the test name is brazilian test?
please answer it because this question is in my exam😊

[@ModellingCareers]

these fractures are certainly growing in tension (Mode I).

[@tamerefe6438]

crack initation has to be in centre of disk, so it is not valid for tensile

[@desmond10241]

why thickness to diameter ratio is not near 0.5?

[@l0chis1]

Given on the basis of the machine that ur using though, is this an indirect load test?

[@hassanhadi8325]

this is called splitting tensile strength

[@hassanhadi8325]

this is called splitting tensile strength

[@savagedeuterium374]

Can anybody help me with the loading situation. Is it applied from both the directions or just applied from top?

[@xpmetal]

It produce force on top , and the force appears below too through the Newton's third law, but it was applied on top to result tesile in material.

[@marcusreis7328]

It's actually a compression force, that turns into lateral tension

[@BiniMerina]

this is purely compression test. to find the compression strength divide the maximum load to contact area

[@AlgoDar]

No brother, this is an indirect tensile test ( though it might seem a compression test but it is not ) . It is called Split Test

[@eternalway9496]

You can clearly see that wings...may be they are used for splitting ..and that's why called splitting test..( sorry not sure though)

[@computername]

I don't believe this can fail just due to pressure. Millions of vehicles drive over concrete every day and it doesent break. I am sure this was blown apart by a nuclear explosion.

[@l0chis1]

This is NOT a tensile strength test....this is compression!

[@RabinTuladhar]

This is an indirect tensile test called as split cylinder test or Brazilian test. It would be very difficult to subject concrete specimen to direct tension force, can be done but difficult. Hence indirect tension test like this one or flexural beam test are used to find tensile strength of concrete.

This surely is a tensile splitting test.

i got an assignment to give the reason for performing tension tests on concrete indirectly, from my university. I searched entire net but couldn't find anywhere but here...lol...it seems funny...
but thank you sincerely...
