Hello, everyone.
This is Enta.
It looks like the performance in Hakata will wrap up without any mishaps or accidents—thank you for all your hard work.
As expected, it's amazing when professionals get together.
I'm truly amazed by the explosive power of technology!
By the way, that vehicle in the photo is generally called a concrete mixer truck.
Civil engineering contractors use ready-mix concrete trucks, right?
I don't really call myself a troublemaker, so I don't say it very often, but,
I feel a little uneasy about the concrete mixer truck.
Since there’s a term called “truck mixer,” I guess that’s correct, lol.
But that's beside the point.
The other day, while I was looking at some photos on Google Cloud,
A photo like this.
I usually inject one dose, but,
At this job site, there were simply too many instances of grout leakage, and
It was a place where even the natural terrain couldn't stand on its own.
So, here's where we put this in.
That's right.
It's NAF-6. That's aramid fiber, isn't it?
These are the fibers used in the simplified method frame.
Since I had quite a bit left over at home, I decided to use it for grouting.
With a standard two-layer vertical grout mixer, you have to load it into the lower chamber, otherwise...
Although this fiber is difficult to use because it clogs the strainer,
It's really convenient to mix it in a drum.
Tips for kneading:Water → NAF-6 → Cement This order makes it easier to stir.
Unlike other fibers, this aramid fiber has a certain amount of weight, and
When stirred with water, it mixes easily without floating.
If you add cement to it, it feels stiffer than the usual fiber-based types.
Even if the grout is leaking, it will rise to a certain level.
It's just really expensive, lol. You can't use it unless you have some to spare, lol.
As for the amount, in this case, four bags mixed together come to about 400 grams.
Actually, I think it was calculated based on some formula at the time, but,
I don't have that document, lol.
It takes about four bags to make a handful.
By the way, even if you double the amount, it just makes it harder to send—the effect remains the same.
The pump used at that time was a Peko Peko Pump.
Well, that's it for now.
