Prevent Freezing by Allowing the Spray Coating to Cure for 5 Hours | Quality Control for Winter Slope Construction
Hello, everyone. This is Enta. We’ve been hit by a major cold snap for the past few days—how is everyone holding up? Here in Nagano, we’re working on a slope at minus 15 degrees Celsius, installing the retaining wall almost directly on the slope. The other day, heavy snow fell again in the afternoon, bringing work at the site to a halt. Snow at this time of year is really tough. Overall, the...
Report on the 1st Construction DX Expo (Part 3) | A Summary of DX Solutions for Use on Construction Sites

Hello, everyone. This is Enta. I’ve been doing mortar spraying on slopes for the past few days, and it’s really tough working with fresh mortar delivered by concrete mixer trucks, isn’t it? I usually order a 1:4 fresh mortar mix instead of dry-mixed mortar, but it starts to harden as time goes by... So I’m trying every trick in the book to get the job done...
Measuring Heat of Hydration Reveals the Effectiveness of Antifreeze Agents | Verification Experiment
Hello, everyone. This is Enta. I’ve been saying this for a while, but I just thought of something good regarding the antifreeze tests. It’s that there’s no need to go to the trouble of conducting experiments on antifreeze—which is meant to prevent freeze damage—on-site, lol. Well, I guess people who know this are probably thinking, “Of course,” lol… In the end, freeze damage…
