No wrong answers, here. I'm curious to know from other concrete engineers:
How do you define "free of vibration" during concrete testing when there is no such thing on Earth, and not even close on a construction site?
I did one online through vccampus, I think, that was about $100 and it was awful. (I got the reinforced concrete.)
An online course cannot help you with the plan reading, in my opinion. If you can read plans well, tab your books, and take that skinny general special inspections reference...
This is in the southeast - so 100 in summer and 20 in winter.
I imagined that the temperature would be a major challenge. That's why I wondered how others were doing this. Are they controlling the temp of the water before it goes in to help? Or using any good hvac?
Working on a large project and keep adding tanks and tanks. I'm looking to set up a humid room. I'd like to do it with a temp building. Someone out there has gone through this and wants to help me out, I know it! I wonder what methods didn't work and which ones did - both for humidity and...
No problem adding super P? I have seen some serious segregation on a couple of sites. I would just be careful with that sort of statement. There. I feel better.
I hope this is right forum... What do you guys make of MVER tests for elevated slabs that are not new (say on the order of 5-10 years old)? I recently tested an 8 year old elevated slab the size of a classroom in a building that is entirely conditioned the same and got an average reading of...
This is a highly-visible project and everything must be by the book. Literally. So I have requested the architect to re-interpret our fill recommendations to exclude residuum in this project site and change the book.
I think one of the lessons learned, here, can be that the geotechnical...
I hear ya. These soils are from the in-place weathering of rock and we have performed some testing (including SPT of course). I will just use a geology textbook to explain soil structure for this type of condition, I guess. Seems like there's a paper on everything else, though! Shucks...
That's closer to what I'm talking about, Dirty. It is residuum being used in its in-situ state. We already performed SPT and stated that the residumm soils indicated in our boring logs would be adequate yadaya. But the spec writer put in 95% of standard. And you may know that this residual...
What I am talking about is soil that has been weathered from rock into its structure and has not been disturbed by man. This soil extends into its parent rock.
My question is about the necessity for compaction testing in residuum. You don't compact residual soils, you leave them in place as long as the exploration indicated that they can support the bearing pressure indicated. A compaction test on residual soils will probably indicate a low failing...
you guys doing homework over here? LOL
Is the freeze/thaw cycle as simple as an area that ever reaches freezing temperatures and above-freezing temperatures? (like everywhere in the US?) or is there a special threshold?
I used to have this great packet of info for wick drains and now I can't find it for anything. Does anyone have a nice tidy reference to design and settlement calcs for wick drains?
