Hello, everyone.
This is Enta.
It finally arrived the other day!
This is it!
As you can see, it's a submersible pump!
But look at this! It’s actually a submersible pump for hot water!!
And here it is, just as winter is about to end lol
It looks like I won't be able to use it until next winter, lol.
Well, I guess there's nothing I can do about it...
The reason I bought this is that,
We have this aquarium with a built-in heater.
I bought this to take full advantage of its performance.
That's because standard submersible pumps are generally limited to water that's warm enough to touch by hand (up to 40 degrees).
If that's the case, I think the mixing temperature of the mortar will be below 5 degrees, based on my estimate.
Since we want to increase the curing temperature as much as possible during the winter months, our target is 10 degrees.
In the case of cement slurry, the final mix temperature is around 20 degrees at a mixing temperature of 50 degrees.
In the case of mortar, since it contains sand, the reasoning is that a temperature of about 60 degrees should be sufficient to ensure a temperature of 10 degrees.
It's amazing that the internal temperature after spraying is 10 degrees during a time when freezing is likely.
I bought this hoping I could try out this experiment, but it looks like I'll have to put it off until next winter lol.
I don't think it gets below freezing anymore unless you go all the way to Tohoku or Hokuriku, you know?
Even if I wanted to take on that job, I'm already swamped with work here, so...
I'll let you know again once I've had a chance to test it.
See you later.
