Split Cylinder Testing (ASTM C496) 

@I know Cause I'm BatMan. exactly this happens due to poisson effect.

We are applying compression in the vertical direction but the cylinder will undergo tension along the length.

100 to 200 psi/min [0.7 to 1.4 MPa/min]

+Rodrigo Adolfo You are correct (and I do state as such in the video); when I made this video, I was a bit pressed for time and made do with what I had. One of these days, I'll go back and rerecord it and introduce a new series of mistakes :) .

12 inch, most likely for a 2:1 ratio

what was the result sir? in numbers.

i also want to know if compressive machine can be use

***** practically there is no such type of loading in the real environment. for example if you take compression and flexural strength testing for concrete, you can find the type of loading in the actual structure. so that you can use the result for decision purpose. to me the test is neither tension nor compression. to assume it is tension test the whole part(body) of the concrete should be in tension force. as you see here the force is applied in a line wise.

Yes, unless your aggregate size is larger than allowed for a 4x8.

cylinder size should be 3 times the aggregate size

The test is an indirect way of determining the tensile strength of concrete since direct methods are somewhat difficult.

+Baldeep Bhullar The ASTM calls for 100 to 200 psi/min, which works out to a load of about 150-300 lb/second.

+Matt OReilly Thank you for your prompt response Matt. Cheers!
