Thank you for posting.. So, the table has to be dropped 25X is that right? at high speed? 'cos i don't have and cannot find ASTM C230.. thank you..

right 25 times in 15 seconds it's quick. You can find this procedure in ASTM C1437, C230 is the specs for the flow table.

Interesting, but that's not ASTM. At least it's not C 173.

Pretty cool looking machine though

As the caption says ASTM C1437 aka "Test Method for Flow of Hydraulic Cement Mortar". ASTM C173 is a Test method for Air Content of Freshly Mixed Concrete by Volumetric method not even close. That cool looking machine is as Flow table made specific according ASTM C230.For your convenience get a new copy of Annual Book of ASTM Standards Section Four, Vol 4.01 & 4.02. You'll be surprised what you've been missing.

This aint a slump test. ASTM C1437 - 07 is Standard Test Method for Flow of Hydraulic Cement Mortar.

There is a slump test ASTM C 172.

There is another test to check concrete's workability - vebe test ASTM C1170.

Technically true as the reference documents speaks for itself. The slump test as mentioned here is a misnomer as often refered by laymen or people who cannot really tell the difference between the two here in our site. Thanks for pointing it out, our european consultants should know better before refering it as a slump.

Look at the slump test that I've uploaded, the video is a lot clearer and there is narration.

[adaminski666]

yup, you're right. I was very wrong

[simpooahder]

Oops, sorry, should be C143 for ASTM slump test. C172 is for sampling.

This is an interesting method... I use the slump test method with the a slump cone with the dimensions 300mm height X 200mm base X 100mm top
