Hello, everyone.
This is Enta.
Do you think chickens molt? lol
I hadn't thought of it that way, but this article was interesting!
Please be sure to check it out.
But that's beside the point.
How many test specimens do you prepare at a time for strength testing?

Normally, one session in the morning or afternoon—three AM sessions plus three PM sessions—is sufficient.
However, in the case of anchor work, depending on when the tensioning work is scheduled, we may make three extra anchors as a precaution.
This is because, generally speaking, the strength test for grout used in ground anchor construction is 24 N at 4 weeks (when using ordinary cement).
Since we can't wait four weeks for the concrete to reach full strength, we use fast-setting cement so we can check it after one week, but,
Sometimes I just can't wait a whole week.
Since we use fast-setting cement, the one-week strength achieved with ordinary cement is reached in just three days with fast-setting cement.
The 4-week strength of ordinary cement is achieved in just one week with rapid-setting cement.
So, as long as you secure 24N in three days, you'll be able to stay on your toes.

If, due to on-site circumstances, you need to apply tension in three days, perform the strength test in three days and then apply the tension.
If a week from now is okay, we'll conduct the strength test in one week.
Since it’s best to be prepared for either outcome so that neither poses a problem, you need to be ready.
You don't need to take both exams (the 3-day and 1-week ones).
Well, unless you absolutely have to collect the data, that is.
It does cost money, but for something like a mold, it's actually quite inexpensive.
Besides, shortening the construction schedule and avoiding downtime would be way more profitable, right? lol
See you later.
