<\/p>\nHello, everyone.<\/p>\n
This is Enta.<\/p>\n
<\/p>\n
Are you making test specimens? lol<\/p>\n
<\/p>\n
Did you know that there are rules governing the preparation of these test specimens?<\/p>\n
To be honest, I hadn't really thought much about it because I didn't know enough, but something happened that prompted me to look into it.<\/p>\n
<\/p>\n
When preparing test specimens, the grout level drops due to bleeding, right?<\/p>\n
If you don't raise the level.<\/p>\n

<\/p>\n
If you built it up, you can cut or shave it down later, so I think it should be fine.<\/p>\n
You need to be careful if the price drops during the \"breathing\" phase.<\/p>\n
<\/p>\n
The dimensional tolerances for test specimens are,<\/span><\/strong>The diameter must be within 0.5 to %, and the height must be within 5 to %.<\/span><\/strong><\/span><\/p>\n That's just the way it is.<\/p>\n For a 50 \u00d7 100 cement slurry test specimen, this means a diameter of 0.25 mm and a height of 5 mm.<\/p>\n <\/p>\n Furthermore, there are specific requirements for the thickness of the capping when performing capping on surfaces with a height of 5 mm or less.<\/p>\n The thickness of the capping layer shall not exceed 2 % of the specimen diameter.<\/span><\/strong><\/p>\n In the case of the test specimen mentioned above, the capping thickness is 1 mm or less.<\/p>\n <\/p>\n That means,It's better to make it a little bigger and then trim it down.<\/span><\/strong><\/span>So that's how it is.<\/p>\n These days, grinders are so powerful that they can cut through things easily. They\u2019re pretty expensive, though, lol.<\/p>\n Like, 500 to 1,000 yen per side...<\/p>\n <\/p>\n Still, it's better than not having any strength at all.<\/p>\n By the way, the rules mentioned above are<\/p>\n Preparation of Test Specimens for Concrete Strength Testing JIS A 1132:2014<\/span><\/strong><\/span><\/p>\n <\/p>\n You can find it if you look it up online.<\/p>\n It doesn't hurt to know this, so please be sure to keep it in mind.<\/p>\n <\/p>\n See you later.<\/p>","protected":false},"excerpt":{"rendered":" Hello, everyone.
