Hello, everyone.
This is Enta.
I've got a SECOM security system! lol
All of these SECOM stickers are managed using sequential serial numbers.
Let's say all of them have serial numbers, and you bought one that had been resold on Yahoo! Auctions or a similar site.
That number tells us exactly which company and which individual received the item.
Everything is under control.
Please be careful.
But that's beside the point.
Let's Try a Wheel Balance Test (Part 1)
Continuing from the other day's post on wheel balancing, today we'll calculate the specific gravity.
When W/C = 50%
| High-early-strength cement | 水 | Admixture |
| 1,230 kg | 590.4 kg | 24.6 L |
Per 1 m³
High-early-strength cement: 1,230 kg
＋
Water: 590.4 kg
＋
Admixture: 24.6 L × 1.128 (specific gravity) = 27.75 kg
= 1,848.15 kg
÷
1000
=1.848
When the specification value is set at ±2.0%
| Lower Limit | Reference Value | Upper Limit |
| 1.811 | 1.848 | 1.885 |
This is, after all, just a theoretical value calculated on paper.
So,
We will actually conduct test installations and test mixes.
In other words, ±2.0% of that value is used as the actual reference value.
While the actual results don't differ much from the theoretical figures, this increases reliability in the field.
So, along with this, we'll track the flow rate to improve quality! lol
Selecting the Right Cement and Flow Tests
See you later.
