Can cylinders be used to test Shotcrete
Can cylinders be used to test Shotcrete
(OP)
I am trying to determine if cylinders can be used to daily test for compressive strength of shotcrete. I understand that test panels need to be done at the beginning of the job for each mix and nozzle-man. Mix is being delivered to the site premixed.
Any help would be grateful.
Thanks
JT

If you want to check the mix design, cylinders are fine. If you want to check the placed properties, cylinders will do no good.
Use hardware cloth forms and shoot into them during placement. They can then be cored and tested.

I was pretty sure that was the answer. I did not see any thing in the ACI concrete manual about cylinders.

I did not see any recommendation on the frequency of testing for shotcrete. Any way you could point me in the correct direction to find the recommended frequency of testing for shotcrete? this is a pretty large project.
