Frequency for Grout Testing

Frequency for Grout Testing

Frequency for Grout Testing

(OP)
Is there a code reference for the required frequency for testing grout at site? For example, once a day .. etc.
The grout will be used at the column base.

RE: Frequency for Grout Testing

A quick look at ACI 351.1R-99 Section 9.2 gives a bit of advice on testing - at least every other day. Please check this spec out yourself.

RE: Frequency for Grout Testing

In USA...

there is a decent argument to be made that grout testing is pointless for most structural masonry built. certainly f'm=1500.

there is also a decent argument to be made that site grout testing is not required by code in most circumstances provided the consistency meets spec and the mix proportions (or design) is acceptable. both of which are required Special Inspections that would occur during continuous observation of grout placement with no additional laboratory testing.

there is a position that i subscribe to that testing firms want to test the grout because 1. they don't know better 2. it gives them something to do that looks like they are providing a service when they staff a job with someone who doesn't understand masonry well enough to provide any value to the project 3. they don't want to create a fuss.

RE: Frequency for Grout Testing

there are a lot of projects that require a bureaucratic array of testing for every single thing too... before i sound too harsh on those testing firms.
