Hello, everyone.

This is Enta.

You do compression strength tests, right?

Where do you crush it? (Meaning, do you perform a compressive strength test?)

Surprisingly, there are differences from prefecture to prefecture, and there are also differences in the philosophies of individual coaches.

So, I’d like to share a thought that I suppose is pretty common.

Compressive Strength at 1 Week and 4 Weeks

Weekly Intensity: Private Ready-Mix Concrete Testing Facility

Week 4: Public Test Site

In cases like this, since the final strength test (at 4 weeks) is conducted at a public testing facility, the local government can rest assured.

The problem, however, is that some prefectures may not have facilities such as public testing centers.

In such cases, the site representative or a government official (or a contractor) is generally required to be present. (Based on the construction plan and meeting minutes)

If it's not a public testing center, and there are daily spray tests, you'll have to go to the testing center every day for a week.

This is a real hassle.

Considering the time involved, I think it would be easier in a way to take it to a public facility, and it would likely be less expensive.

However, while the costs at public testing facilities are higher than those at private ready-mix concrete testing facilities,

Considering the peace of mind and how well the government offices treat you, I’d definitely recommend the public test center lol

The important thing isAccuracy and FairnessI think this is the case, so it seems to me that this way of thinking is essential for those of us working in public works.

Conversely, I believe private-sector construction projects use private ready-mix concrete testing facilities.

However, since I'm dealing with the general public, I figured they probably wouldn't understand anything too difficult (or highly technical), so,

It seems to me that there are many cases where tests at private ready-mix concrete testing facilities are conducted in a way that attempts to cover things up.

Personally, I don't like being suspected of that kind of thing, soBasically, they're all public testing centers.That's right.

Even if it costs a little more, trust and credibility are important, so,

We confidently have our own products tested by an independent, third-party public agency!

That kind of spirit is important, isn't it?

See you later.
