Personally, I belong to the W.C. Fields barbering school of
dermatology, though the straight razor has been replaced in
modern times with the Dremel tool's cutoff wheel.

Those who have access to better tools prefer to use a microtome to
plane the surface after applying LN to freeze the target. It's just
like peeling a potato, except that you don't have to listen to the
vegetables screaming.

This moment of semipseudosurrealism has been brought to you by The
Committee To Bring You Things That Only They Want To Support.

In on-grade slabs, the surplus water tends to either soak through into
the base (unless, of course, there's a water barrier present, which in
road construction is now commonly the case) or pool on top during the
leveling procedures. [snip]

A water barrier under pavement - that sees rather odd. Pavements are
best supported over a free-draining granular base - water is the enemy
of proper subgrade support.


The standard spec for high-traffic Interstates has been modified, at
the very least for for wet climates (and possibly elsehwere), to
include a continuous asphaltic concrete underlayment below the
long-slab reinforced concrete road surface. This goes a long way
toward preventing the large pothole formation commonly seen with older
methods, where joint flexure may cause pumping of rain and mel****er
which can degrade many free-draining bases easily. It also provides a
more stable bed for the road surface layer. To work well, it requires
that the recipe of the concrete used must be tightly controlled, and
the suppliers have had to fine-tune the mix loading accordingly.

Calling a stabilized base a moisture barrier is somewhat unusual
terminology, as it serves a significant structural function in addition
to being a low permeability layer.

Vapor barriers are very common under grade supported slabs in buildings,
however. The best curing method is to cover the floor in burlap after
finishing, and replenish water as needed to keep the burlap moist.
Otherwise, excessive slab curling will result from differential curing.


The same burlap-layer technique of surface mosture maintenance is
sometimes used for the long-slab reinforced concrete road surfaces. I
have been told that there is also an evaporation-reducing coating that
is sprayed on these surfaces while they're still curing, but I'm not
entirely sure that the information source was correct about the nature
of what was being used.

There are "curing compounds" that can be sprayed onto new concrete that
are supposed to prevent moisture from evaporating, but their
effectiveness has been called into question.

Concrete is interesting stuff; it looks deceptively simple, but there
are a lot of nuances to getting it to work just right.

My favorite form of concrete is puffed rice squares - they are an
aggregate matrix with a cementituous binder after all.

I'd say not; if you had an elaborate process for cleaning the bike,
which you performed whether the cat had sat on it or not, then it
would be ritually clean.

Cat's not allowed in the bike room; does disassembling and individually
cleaning the chain links count as elaborate?

I do actually disassemble the cassette and clean the individual cogs.

And in their commercial form, probably almost as nutritious as the
Portland variety, though presumably lacking in calcium....

Okay, I think we killed this one. Back to bikes...

I'd say it darn near qualifies as OCD if done more than once.

Ah, yes, but do you reinstall the rivets afterwards? (Disassembling
hardly counts if you're already in loose mode, but I'll call it a
ritual if the cassette has screws that get reinstalled.)
