Bags On Supports?

It's really foggy on the webcam right now, but why are there bags on Maverick's supports?

Is it cold up there? Maybe they did the "second pour" of concrete on those supports and they covered them to keep in the heat.

How about a Touch-up Paint job on the supports, that's my guess.

From my understanding, when the supports were installed, there were gaps between the support and footing, as seen here. Those gaps have likely been filled in, and they are letting that substance dry.

Hey, I already mentioned this!:)

Doggie Bag anyone?????? Paper or plastic?????? Make sure you recycle your bags!!!!!

Maverick was designed to have spaces, so it can "sink" in the future :)

djDaemon is right... There is a gap between the bottom of the round base of the support and footer when it's installed. The support is actually standing on that "+" shape sticking out of the bottom. Once all the track is complete, that gap is then filled in with concrete.

No matter how hard you try, there will be slight high points and low points in the top of the finished concrete pier. If you were to rest the column on this uneven surface, the steel base plate would bear on the high points only. Under load, the steel base plate would try to span across the high points, which puts very high residual stresses in the base plate for which it was not designed.

To avoid this they temporarily support the columns on steel shim plates and then fill the gap between the two with a non-shrink grout, ensuring that there are no voids or cavities. This ensures that the stresses are constant through the entire column base plate, and also that you get 100% between the base plate and into the concrete pier.

Awesome. Thanks for the info, Mr. Engineer.

Do you happen to know what the "non-shrink grout" is composed of?

^ A 50-50 blend of cotton and asbestos ;)

I was woundering that to about them?

Non shrink grout is close to a six bag mix of concrete as opposed to the normal five bag mix of concrete.

You may be asking yourself what is a six or five bag mix, well in one yard they either use five or six bags of piedmont cement, thusly a five or six bag mix.

Also with the grout they will use very small or no aggregate (rock) to make it easier to pack the void.

I see. Thanks, David.

Never know when knowlegde of concrete will come in handy.:)

Like, what's the best kind to fill these here shoes with...?

Normal portland.:)

^^ As one of the guys I used to work with would say,(insert Italian accent) " I can make anything out of concrete! What size shoe do you wear?

by the way exit I would suggest a five bag mix with heavy rock!

Heavy rock? That would be in contrast to light rock I suppose? I'd rather light rock myself - much easier to carry.

Is heavy rock more like Iron Maiden or Slayer? Light rock would be Bryan Adams.
