Self consolidating concrete (SCC)

#1
Question If it is true that SCC has lower permeability than normal concrete, does this mean it dry's slower?
Question Thus resulting in less curling? Or are shrinkage reducing admixtures still greatly needed?

Certainly looks to me that SCC can't be used over a sand blotter layer... which seems like a very good thing for Div 9 people.

Question Is SCC to be tested differently for moisture?

Question Do moisture sealing companies treat SCC differently?

Question Any other things I should know?



Amazing stuff to see on YouTube about SCC.

I think concrete construction is doing an issue on it. That is the current poll on: http://www.concreteconstruction.net/

I never came across the stuff myself. I'll look into it to see how I would be affected in the mitigation biz....

SSC concrete is a low w/c ratio highly plasticized concrete. It is amazing how it flows and yet the coarse aggregate still remains suspended. The heavy pours do not need to be vibrated like normal concrete. It does dry faster than normal concrete because of the low w/c ratio and less water.

I bet it is not used in residential applications. How would a guy even know by looking at it? The GC probably does not even know unless the architect told him. And even then would he tell you?

This is where residential and commercial are distinctly different.

I would also like to know if the normal testing is even accurate.

Good question Stephen, I've never seen it. It has to be expensive!

Hey, ea, thanks for that link. I've been looking into doing some concrete countertops for my house. There was one on youtube on the right with the superplasticizer.

It's gives you a really good idea of how the superplasticizers works. Check it out!

Pretty cool video of superplasticizer in action!

I did a concrete counter top in my bar. I just ground it and exposed aggregate and inset a rope light around the outside edge. The whole 10' long top cost me about $35. LOL
