Unfortunately I wasn't part of the project, that was the explanation the city gave me when I called. Ripup was already in progress.
Thanks for the brand name - I was aware of the products in general for overlay, but haven't used any.
The perfectly good sidewalk near my house had to be entirely ripped up and replaced when the road was redone, because of a cross-slope varying up to 2.1%
Your phrasing is difficult for me to follow.
If I am reading it correctly, you calculate that the actual, applied wet paint will need to be 100 liters.
If you have 60% wastage*, that means the 100 liters is 40% of the paint you need to purchase. Divide 100 by 0.40 and you get 250 liters you...
Interesting. Bridges in Texas almost never have field welding. All bolted. They are supposed to do fitup in the fab before the girders are shipped.
The Margaret Hunt Hill bridge was field welded, but that was architect-driven.
VOCs regulations are orthogonal to the name of "Volatile Organic Compounds"
Effectively, solvents are exempted from VOC by the US EPA because their contribution to ground-level ozone is below an arbitrary threshold. Some areas (SCQAMD) use actual ozone-forming activity for restrictions rather...
Agreed with moltenmental.
Talk to the industrial rep for any major paint manufacturer and they can recommend paint systems based on a zinc-rich primer.
Note that IOZ primers are typically less tolerant of over-thickness than epoxy zinc primers.
I'm not sure why producers would always include...
I'm confused by your chloride levels. It appears you are saying they are less than 2 million parts per million - assuming the commas are correct, not the zeroes. Which is true of anything, even pure chloride (if you could create it) maxes out at 1 million parts per million.
Corrosion resistance...
The leaves, stems and flowers have quite a bit of latex.
*shrug* If they want to deal with more expensive machinery, slower growing cycles and more contamination (dirt) - go with roots too.
Instead of digging up the tap roots, might just collect the tops and let the leaves resprout. Should take less energy and speed up harvests. Might manage a monthly harvest, with no replanting.
Yeah, the concrete guys here had a presentation on chlorides for freeze resistance - they don't think the corrosion tradeoff is generally worthwhile in our environment. Entrained air microbubbles was the preferred solution. But it's certainly not a settled subject, and we have less freeze/thaw...
Who the heck pays $1 USD per kWh for grid electricity? I'm paying $0.10
One nit: Why do you bother using Wh as a unit for most of your stuff, and kWh for the cost? Why not just use kWh throughout?
If you discharge @ 5kW for 1 hour, you need 6.25kWh to recharge at stated efficiency. Around...
Even after oxidation, the zinc may do something. Zinc oxide can act as a moderate corrosion inhibitor.
However, the real way to do this is to put together a bunch of connections with and without the grease, put them in a slightly harsh environment and see what happens.
The mountains of tires have been rapidly depleting in Texas - some for crumb rubber in asphalt, some other small uses - but most of them are going into the cement kilns as fuel.
