How to specify Self Consolidating Concrete
How to specify Self Consolidating Concrete
(OP)
I've found a bit of literature about self consolidating concrete. I'd like to use it on several exposed columns, but can't find any really helpful information about specifying it. The closest I found was
http://www.nrmca.org/aboutconcrete/cips/37p.pdf
which is quite informative, but the specifying section wasn't quite enough. There are several European or Japanese specs on it, but I'm not sure how they conform to ACI. In talking with a local concrete supplier, I need to specify the strength and slump flow of the concrete, and that is all (other tests include resistance to segregation, and viscosity). ACI committee 237 is putting together a guide to specifying SCC, but until they put out a guide to specifying and testing the concrete, I'm hesitant to use it.
Has anyone else specified SCC, and if so, what exactly did you specify? And what did you specify in terms of testing?
Thanks

Ross Bryan Associates in Nashville, TN audits for PCI. They may be of help.
Good Luck.
RE: How to specify Self Consolidating Concrete
We specified
- slump (flow) wich will depend on your formwork and reinforcement configuration
- Strength
- Segregation (there is a segregation index)
- Air content (as per normal concrete)
- Temperature (as per normal concrete)
