Reasons Why Test Dough Mixes Fail | Checking the Recipe
Hello, everyone. This is Enta. You often conduct 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 conduct tests to determine whether that mix will achieve the required strength and whether it meets the standards. There are some surprisingly common reasons why these tests tend to fail…
Curing Cement Slurry | Winter Construction
Hello, everyone. This is Enta. The other day, I conducted an experiment. It was a compressive strength test. The experiment involved observing changes in early strength using the same mix design. That said, it was simply a matter of whether or not to leave the test specimens as they were after taking them. I left these test specimens as they were until morning…
A Thicker Cement Slurry Is More Effective | Tips for Mixing
Hello, everyone. This is Enta. You know how you take test specimens (cement slurry) at job sites, right? Like for ground anchor work, rebar insertion, or piles. There are all kinds of projects, but when you’re making these test specimens, if they’re extremely soft, you just throw them away, right? lol But on the other hand, if they’re on the hard side…
Found a Great Product! (OKM-50L Water Flow Meter) | Grout Management
Hello, everyone. This is Enta. Do you use water meters? Lately, I’ve been seeing them used quite often in ground anchor construction projects and for shotcrete work. I even tried using one at a job site I was working on the other day. The reason is that if the general contractor awards points for innovative ideas, I try to use them as much as possible…

Water Used in Concrete Mixing | Quality Control
Hello, everyone. This is Enta. How do you handle the water used for mixing grout, mortar, sprayed concrete, and the like? As for the water we use, we rely on mountain spring water, river water, lake water, and tap water. I imagine we’re using freshwater—anything other than seawater. Of course, we don’t use rainwater…

A Moment from the Compressive Strength Test | Test Video
Hello, everyone. This is Enta. The other day, we conducted a compressive strength test. It was the 3-day strength test as part of the basic testing. The results showed an average of about 38 kN, so there were no issues. Also, this time, I captured the moment the test specimen burst. Here’s what it looked like! I’ll share this as a video…
This Is What Happens with Standard Spacers | Product Comparison
Hello, everyone. This is Enta. The slope we worked on last year collapsed, lol. Well, it happened a while back, but I went to check out the site the other day. As you can see, this is the rebar insertion work we installed. In reality, the collapse started much further back, so the rebar insertion work wasn’t enough to handle it…
