Self Consolidating Concrete
Self Consolidating Concrete
(OP)
I have a small repair job for replacing some concrete elevated curbs/handrails. The contractor is suggesting using self-consolidating concrete. I had never heard the term before so I googled it. It appears to be a mix with HR water reducer and viscosity modifier. The only problem that I could find in my web search was that it is expensive.
Has anyone specified or allowed this mix on any of your projects? Any problems, issues?
Thanks.

RE: Self Consolidating Concrete
On the design side nothing magic about SCC, it's just design as usual. In the field it can be a little more tricky. Formwork needs to be tighter and more heavily built due to increased wet pressure and avoid excessive "slobber". It is so fluid the stuff isn't measured by slump it's measure by spread, say like 24" or more. Generally it's highly architectural applications where SCC finds it's best application. It can be tricky handling. Does you project seem to warrant this sort of thing? Your sub might just be thinking a small project might be the right spot to get a little experience, maybe?

SCC is truly amazing. When it works like it's supposed to. Which is most of the time, but not all the time.
