Curing of Sprayed Mortar Test Specimens | Quality Control
Hello, everyone. This is Enta. The other day, I wrote about curing cement slurry test specimens. Curing Cement Slurry Come to think of it, I haven’t written about curing sprayed mortar yet, so I’ll share my experience here. Sprayed mortar test specimens are huge, you know…
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…

Could You Become a Waterproofing Specialist? | Diversification in the Slope Stabilization Industry
Hello, everyone. It’s Enta here. I’ve gotten pretty used to water stoppage now, lol. Since we’re short-staffed at Enta, I’m also doing construction management on-site, and I’m handling the water stoppage right behind the drilling crew. I’ve gotten pretty used to it. I’m starting to be able to stop the water even when it’s gushing out like this…

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…
Drilling Limits with Spring Drills (Part 2) | Continued Analysis
Hello, everyone. This is Enta. Regarding the spring drill boring I posted about the other day—it actually went well in the end, lol. It was a 17-meter borehole in sandy soil. The borehole diameter was φ115. It went surprisingly smoothly. (There’s a trick to it, lol.) Well, since the drilling angle was a vertical 90 degrees this time, I thought…
