<\/p>\nHello, everyone<\/p>\n
This is Enta.<\/p>\n
Are you all okay there in the Tohoku region?<\/p>\n
The destructive power of a linear rainband is insane!<\/p>\n
<\/p>\n
Please be very careful!<\/p>\n
But that's beside the point.<\/p>\n

I believe we add color powder when coloring the slope. (If specified in the design.)<\/p>\n
When you add magnesium oxide-based color pigments, the result can vary\u2014sometimes it turns reddish, sometimes blackish, and so on, right?<\/p>\n
It's like they're trying to make it look green depending on the region... (Is this China!?)<\/p>\n
<\/p>\n
In particular, there are places where it\u2019s used near the coast, and<\/p>\n
I think people with a slightly unconventional mindset (like architects or government officials) might go for white mortar, lol.<\/p>\n
I've heard a story about how the mortar on the beach glows white and there are fish there\u2014is that true??<\/p>\n
<\/p>\n
As for what happens when you add this colored powder\u2014well, the color does change, of course, but...<\/p>\n
In my experience,It'll mess up the formula!<\/strong><\/span><\/p>\n When you add colored powder, the mortar starts to get sticky, which makes it harder to spray.<\/p>\n As a result, there will inevitably be either more sand or more water.<\/p>\n <\/p>\n What happens then is that the strength clearly decreases (especially in areas with poor-quality sand), making the structure more prone to cracking.<\/p>\n It peels off in small pieces here and there and falls off.<\/p>\n This also causes cold joints at the weld seams, resulting in a rather poor condition.<\/p>\n I've never seen a formwork in decent condition made with mortar mixed with colored powder lol<\/p>\n The surface is all chipped up, isn't it?<\/p>\n <\/p>\n If you're thinking of adding colored powder, I wouldn't recommend it lol<\/p>\n What's more, the color unevenness is really bad.<\/p>\n Daily variations in temperature and humidity, soil temperature, water content, and surface moisture content of the sand.<\/span><\/strong><\/span><\/p>\n It's practically impossible to make this uniform\u2014it's 100% impossible, so you can be 100% sure there will be color variations lol.<\/p>\n Every time a building is completed, the inspector always says, \u201cIs this color variation really okay? Can\u2019t we do something about it?\u201d<\/p>\n <\/p>\n And a few years later, it was falling apart lol<\/p>\n I really don't know what's good anymore, lol.<\/p>\n The sprayed mortar I happened to come across the other day was in terrible shape\u2014it had been patched up countless times and was in a really bad state.<\/p>\n <\/p>\n What's more, the color pigments fade when exposed to UV rays.<\/p>\n It actually starts to turn whitish, so I started wondering, \"Is this even worth it?\" and,<\/p>\n Plus, when it gets all worn out over time, the freshly colored mortar underneath shows through, making the color even more uneven lol<\/p>\n <\/p>\n Personally, I'm against adding colored powder.<\/p>\n There's not a single good thing about it.<\/p>\n I just think it's a waste of money on public works projects.<\/p>\n I think there are probably a lot of people who feel that way.<\/p>\n <\/p>\n Let's be extra careful with the colored powder when applying it, okay? Should we remove it??<\/p>\n <\/p>\n See you later<\/p>","protected":false},"excerpt":{"rendered":" Hello, everyone. This is Enta. Are you all okay there in the Tohoku region?
