If you don't lift the cone slowly, how else are you going to pass a crappy slump from one of your buddy concrete truck drivers!? (jk)

Oh yeah, this is the CSA standard, so if you're following some sort of other standards organization, your results may vary....

I guess tecnicaly you don't rod through the entire first layer as you will hit the base plate, but you go down as much as you can without hitting it.

This is a pretty good slump test. I noticed a few things though

- when placing concrete in the slump cone, it is best to twist the handle of the scoop as it is falling in.

- The bottom of the cone should be cleaned off, front and back, before lifting the cone

- He said verbally, he would rather a see a slow pull. If you pull the cone up too slow you will not have accurate test results. It will give a lower slump than what the concrete actually is.

@wxyzxdll

you are such an ignorant.

[wxyzxdll]

only gay people do a slump test. Experienced concretors can tell just be the consistency.

Mistake Number 1: He used a sheet of plywood. The baseplate must be of a non absorbent material.

Mistake Number 2: He was not setting his layers in equal volumes. Not even remotely close to equal.

Mistake Number 3: You do not need to retest if your cone tilts. 85% of the time it will be completely displaced as most pours aren't anywhere near that dry. I used BB's to mark the displaced center as an entry level technician when I started.

Poor example of a slump.
