Guidelines for Diluting Cement Slurry with Hot Water Based on Finished Mix Temperature

Hello, everyone. This is Enta. I received an email regarding the discussion we had the other day about mixing mortar with hot water. The question was, “What about grout?” Based on my experience, I think using cement milk is a viable option—especially when working in extremely cold conditions. I ran a simulation using mixing water at 50°C. Simulation…

The Real Reason It Comes Out From the Outside of the Casing After Pressure Injection!

Hello, everyone. This is Enta. Are you doing pressure grouting? Well, I’ve always said that pressure grouting isn’t all that effective, but since the topic of “Why does it come out of the mouth?” came up, I thought I’d write about it. Drill the holes as usual, and for ground anchors or…

Transparent construction management and transparent safety management instill a sense of security in others.

Hello, everyone. This is Enta. When doing ground anchor work or rebar installation, you put leftover grout and other materials into ton bags for disposal, right? When you do that, it usually looks something like this everywhere. We used to do it this way, too. No, wait…

Reasons Why Test Mixes Fail

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…

Drilling with cement slurry in ground anchor construction

Hello, everyone. This is Enta. I’m so happy to hear that a construction site we worked on as a first-tier subcontractor this spring was recently recognized!! The general contractor was thrilled and reached out to let us know. I’m just so happy! This is what makes being a subcontractor so rewarding. The general contractor gets recognized by the local government, and we get recognized by the general contractor. I’ll work even harder…

How to Calculate Cement Slurry and the Loss Rate

Hello, everyone. This is Enta. I used to have a grout calculation website, but I shut it down, so people still mention it to me from time to time lol. So, I’ll list the minimum necessary coefficients here. However, since that alone would make the calculation method a bit bland, I’ll include the full method as well. Borehole diameter (…

What on earth is 1,230 kg of cement slurry?!

Hello, everyone. This is Enta. What Is the Mix Design for Cement Slurry? | A W/C Ratio of 50% Is the Standard for Slope Stabilization Work. To begin with, cement slurry is a paste-like grout made by mixing cement powder and water. In slope stabilization work, it is used in ground anchor work, rock bolt work, rebar insertion work…

Please enjoy the Vietnamese-language version of the video on how to make cement slurry.

Hello, everyone. This is Enta. I’ve finished the Vietnam-themed version of the “Cement Milk” video I shot the other day, so please take a look. Well, it might be hard to understand just from this, so next time I’ll shoot a more in-depth video! I want technical interns from Vietnam and other countries to understand…
