Hello, everyone
This is Enta.
Are you all okay there in the Tohoku region?
The destructive power of a linear rainband is insane!
Please be very careful!
But that's beside the point.
I believe we add color powder when coloring the slope. (If specified in the design.)
When you add magnesium oxide-based color pigments, the result can vary—sometimes it turns reddish, sometimes blackish, and so on, right?
It's like they're trying to make it look green depending on the region... (Is this China!?)
In particular, there are places where it’s used near the coast, and
I think people with a slightly unconventional mindset (like architects or government officials) might go for white mortar, lol.
I've heard a story about how the mortar on the beach glows white and there are fish there—is that true??
As for what happens when you add this colored powder—well, the color does change, of course, but...
In my experience,It'll mess up the formula!
When you add colored powder, the mortar starts to get sticky, which makes it harder to spray.
As a result, there will inevitably be either more sand or more water.
What happens then is that the strength clearly decreases (especially in areas with poor-quality sand), making the structure more prone to cracking.
It peels off in small pieces here and there and falls off.
This also causes cold joints at the weld seams, resulting in a rather poor condition.
I've never seen a formwork in decent condition made with mortar mixed with colored powder lol
The surface is all chipped up, isn't it?
If you're thinking of adding colored powder, I wouldn't recommend it lol
What's more, the color unevenness is really bad.
Daily variations in temperature and humidity, soil temperature, water content, and surface moisture content of the sand.
It's practically impossible to make this uniform—it's 100% impossible, so you can be 100% sure there will be color variations lol.
Every time a building is completed, the inspector always says, “Is this color variation really okay? Can’t we do something about it?”
And a few years later, it was falling apart lol
I really don't know what's good anymore, lol.
The sprayed mortar I happened to come across the other day was in terrible shape—it had been patched up countless times and was in a really bad state.
What's more, the color pigments fade when exposed to UV rays.
It actually starts to turn whitish, so I started wondering, "Is this even worth it?" and,
Plus, when it gets all worn out over time, the freshly colored mortar underneath shows through, making the color even more uneven lol
Personally, I'm against adding colored powder.
There's not a single good thing about it.
I just think it's a waste of money on public works projects.
I think there are probably a lot of people who feel that way.
Let's be extra careful with the colored powder when applying it, okay? Should we remove it??
See you later
