Hello, everyone.
This is Enta.
It's gradually getting hot and humid, isn't it?
If you start taking measures against the heat around this time, you'll be able to enjoy the summer without overexerting yourself.
Preparation is everything!
But that's beside the point.
In quality control, there is a control item called "flow rate measurement."
The standard range is 10 to 18 seconds.
There are differences depending on whether it's rail or road transportation, but the maximum is between 9 and 22 seconds.
So, most people keep it around 14 seconds, right? lol
Why is it set to around 14 to 16 seconds?
Quality Control Scores
In this case, isn't the average figure ultimately...It looks nice when you organize your documentsRight?
It’s the same for any construction project, but a while back, the government started awarding points for projects that fell within the standard values of 80% and within 50 percent.
As expected, as a result of the government agency’s efforts to differentiate the scores,
Manufacturers are also making efforts to keep their products within the specified limits in order to earn points.
By doing so,The precision and quality of the finished products themselves are steadily improving.So it's not a bad thing.
How to Establish a Standard for Measuring True Flow Rates
This is standard practice at companies like NEXCO, but,
We'll conduct a test mix using the mix design for that specific job site.
We use the results of the test runs as the average value and use that value as the benchmark for our management.
Doing so will help minimize inconsistencies on-site and ensure you won’t be caught off guard if government officials come to inspect.
Key Points
This is important, but it depends on weather conditions such as temperature and humidity.
Variations tend to occur during seasonal transitions, such as from the rainy season into summer.
At that time, it’s fine to conduct a test run and adjust the average value.
The reason is clear: because the temperature has been fluctuating, the flow no longer matches the current conditions.
However, if the numbers are too fast or too slow, something is wrong.
Please be especially careful if you're in a hurry.
Also, please be aware that the falling speed differs significantly between ordinary cement and fast-setting cement.
This was a while back, but I used to handle a lot of detailed administrative tasks on-site for the Ministry of Land, Infrastructure, Transport and Tourism.
Being young was so great lol
As I was writing this, it occurred to me that I think the stirring time is more than 2 minutes, but,
There aren't any companies that strictly stick to a 2-minute time limit, are there?
Set the timerInnovative Approaches to Improving Grout QualityWhat do you think about that?
(I'll give this a try next time! If anyone's already done this, please send me some photos. I'd love to copy your idea lol.)
See you later.
