Is that really the right material to use for the filling?!
Hello, everyone. This is Enta. Today, I’m going to talk about this lol. “Huh? What???” You’re probably thinking that, right? Yes. It’s about filling in the gaps. Basically, when it comes to rebar insertion or ground anchor work, grouting is done only up to the horizontal level. Anything beyond that…
Just don't add water!
Hello, everyone. This is Enta. When you’ve mixed a few batches of grout, the grout left in the mixer tends to get pretty hard, right? What do you do in that case? This video shows what happens when you add something to that hardened grout! At first, it’s all clumpy…

Hello, everyone. This is Enta. I’m getting hammered by pollen, lol. But anyway, are you practicing for the exam?

Hello, everyone. This is Enta. Are you all okay there in the Tohoku region? The destructive power of that linear rainband is unbelievable! Please be very careful! But anyway, when we color slope surfaces, we usually add color powder (iroko) (if it’s included in the design). Magnesium oxide…
No matter where you buy cement, it meets JIS standards.
Hello, everyone. This is Enta. Our industry uses a lot of cement, doesn’t it? Plus, with material costs rising so rapidly lately, it’s really tough, isn’t it? The other day, I went to a home improvement store and found that their cement was actually cheaper than what we buy, lol. That’s per bag…
Thoughts on the Cross-Section of a Sprayed Mortar Worker | Analysis

Strength with and without Formwork | Verification of Formwork Construction
Hello, everyone. This is Enta. In my blog post the other day, I said I was planning to post a video of an experiment today, but when I really thought about it, I usually write most of my posts the day before. So, it’s impossible for me to write about something that happened today on the very same day. Maybe tomorrow… (probably lol) Anyway…

Hello, everyone. This is Enta. “Rapid-setting cement” is a term that always makes it into the top 10 search results come winter. I’d like to take another look at this topic, drawing on my previous articles as well. Rapid-setting cement is estimated to reach a strength equivalent to that of ordinary cement after 7 days in just 3 days or more. Ordinary cement’s 28…
