Post-processing of test specimens after preparation for the compressive strength test
Hello, everyone. This is Enta. Are you conducting compressive strength tests? Well, I’m sure you are, lol. I think most veterans already know this, but there are some preparations to make after coring. If you skip those steps, the strength may decrease or the test may fail to yield a valid result, so let’s go through the steps…
Calibration (Adjustment) of the Mad Balance
Hello, everyone. It’s Enta here. People often ask me, “How do you manage to write every day!?” Well, that’s exactly it. I do write every day, but I really have to rack my brain for ideas, lol. Sometimes I run out of ideas. That’s actually pretty tough, you know~ So, a friend of mine asked me about 〇〇…
Test Method for Flow Tests Conducted After Mixing Cement Slurry
Hello, everyone. This is Enta. Do you know how flow tests are conducted? Since there are actually quite a few people who don’t know, I’ll try to explain it. But I think a video would probably make this easier to understand. That said, I can’t shoot one right away, so I’ll just write it out this time lol. Sem…
I tried filming a video on how to mix cement slurry!
Hello, everyone. This is Enta. I’m going to share the recipe for cement milk that I filmed the other day lol. It was super windy that day, so it was a real struggle lol. I kept thinking, “Are you serious? Filming on a day like this?” but for various reasons, I just had to do it that day. As for the steps to mix cement milk, it’s simple…
Reasons Why Test Mixes Fail
Hello, everyone. This is Enta. You often do test mixes at job sites—like those run by NEXCO or the Ministry of Land, Infrastructure, Transport and Tourism—right? You submit a mix design, and then you run tests to see if that mix will achieve the required strength and whether it meets the standards. That’s what we call a “field-adjusted mix.”  …
What exactly is an on-site adjustment to the mix in spray-applied concrete work?
Hello, everyone. This is Enta. It’s November already!!! Only two months left in the year! Let’s give it our all at work ^^ But enough of that. In this post, I’d like to write a bit about adjusting the mix ratio for spray-applied coatings. You know how they adjust the mix ratio on-site at spray-coating jobs, right? &…
How to Pour Cement Slurry Quickly and Accurately on a Sloping Mountain!
Hello, everyone. This is Enta. When the cement slurry doesn’t rise during rebar insertion, what do you do? I don’t think many of you just keep pouring the cement slurry without doing anything. After all, you want to get it up as quickly as possible! lol So, what do you do…?
If the cement slurry turns out too stiff when you're making it, don't add just 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…
Optimal Flow Test Values | An Approach to Optimizing Mix Designs on Site
Hello, everyone. This is Enta. It’s been pretty hot lately, hasn’t it? I just went from Tokyo to Shizuoka the other day. It was a scorcher, and I was drenched in sweat!! I’d love for you to hop on the Shinkansen sometime this fall, lol. But anyway… As for what constitutes an “appropriate” flow rate, basically it just means staying within the specified range…
