Hello, everyone.

This is Enta.

Today is the last day of work for almost every company, isn't it?

Our work on-site ends today, too.

As the end of the year approaches, don't you just feel like going shopping?

I don't usually care about it at all, but then I suddenly get the urge to have it lol

A long time ago, I...Ever since I got scammed on Yahoo! Auctions at the end of last year, I’ve decided I’ll never shop at the end of the year again!Like...

I've decided, lol

Nothing good ever comes from buying in a hurry.

That's why you often hear in sales pitches...

"If you buy it this week, you'll get 10% off!"

"If you decide now, you'll get a discount."and so on

That kind of stuff is mostly just a load of crap, lol.

I used to get tricked by that all the time lol

There are tons of salespeople who say the same thing the next day, lol.

I won't spend any money during the New Year's holidays!

With this, I'll save up some money next year and buy a machine lol

But that's beside the point.

That's the absolute basics of slope engineering, isn't it?

 

Have you ever stopped to think about why you're doing this?

When I was young, I used to go to the job site without giving it a second thought, and

I was putting up lath with the subcontractor's foreman.

For about three years, I was a supervisor, craftsman, and jack-of-all-trades, lol.

Thanks to you, I've learned a lot of things.

What I learned led me to wonder, “Why am I doing this?”

This becomes clear when you consider the properties of concrete and steel.

This is just common sense, but,

Properties of Concrete = High Compressive Strength

Properties of Reinforcing Bars = High Tensile Strength

Right?

Combining these elements creates a composite structure that is resistant to both compression and tension.

That is how it acts against external forces.

There is a type of temporary spray-applied lath without wire mesh that’s 3 cm thick, right?

You can easily break that with your foot.

However, if you add some wire mesh to that, it will be less likely to break.

 

Also, by adding the wire mesh,Continuity of the Entire Slope...will appear.

In other words, it protects the entire slope from external forces.

Even if partial collapse occurs, the presence of the rebar mesh ensures that,

Because there is continuity, the structure is designed to handle the whole.

It also serves to prevent parts from peeling off or falling due to deterioration.

 

However, it's just a 2mm steel wire, after all.

Since strength cannot be expected, no strength calculations are performed during the design process.

 

When using spacers, you position the lath in the center, right?

Actually, reinforced concrete is structurally stronger when the rebar is positioned as close to the outer surface as possible.

If you ignore the concrete cover, cracks are less likely to form on the outer surface when subjected to external forces.

Therefore, when performing construction work such as sprayed mortar,

This means that if the wire mesh is closer to the surface than to the center, it is less likely to crack.

However, no verification has been conducted for sprayed mortar.

However, it is a fact that the addition of fibers and other materials reduces the number of cracks.

The fibers run through the entire cross-section all the way to the surface, right?

 

See you later.
