<\/p>\nHello, everyone.<\/p>\n
This is Enta.<\/p>\n
<\/p>\n
Do you measure flow rates?<\/p>\n
<\/p>\n
I think it often happens that results from this flow test don't fall within the specified limits.<\/p>\n
Especially on hot summer days, lol<\/p>\n
<\/p>\n
First, let\u2019s start by answering the question, \u201cWhat exactly is this flow rate measurement (flow test)?\u201d<\/p>\n
This product, called P-Rote, is used for injection mortar and paste...Flow Test Equipment<\/span><\/strong><\/span>That's it.<\/p>\n P-Loop = P-Funnel.<\/p>\n This is used to measure the flow properties of low-viscosity pastes.<\/p>\n <\/p>\n Liquidity is sometimes referred to as \"workability,\" right?<\/p>\n Workability refers to ease of work<\/span><\/strong><\/span>represents.<\/p>\n Another aspect we measure is consistency.<\/p>\n Consistency is a property of materials<\/span><\/strong><\/span>That's it.<\/p>\n <\/p>\n A flow test reveals these two things.<\/p>\n <\/p>\n For example, we conduct a test run and set a midpoint value.<\/p>\n If it's 13 seconds, then within \u00b14 seconds of that value, it would be somewhere between 9 and 17 seconds, right? (At that location)<\/p>\n If the result falls within this range, we can conclude that the target consistency has generally been achieved (and the strength is also adequate).<\/p>\n In numerical terms, if the value is low, it may indicate that \u201clow concentration = low intensity.\u201d<\/p>\n Therefore, the darker the color, the higher the strength tends to be (due to a higher cement content).<\/p>\n That said, it\u2019s only a matter of a few seconds, so it\u2019s not a big deal.<\/p>\n Normally, concentration is measured using mud balance, but it can also be determined to some extent by measuring flow rates.<\/p>\n <\/p>\n If the number is too high, it means that workability has decreased.<\/p>\n However, personally, as long as the grout pump can handle it, I'm fine with it being thick.<\/p>\n <\/p>\n This means that even if the value exceeds the limit, the strength will still increase, so there's no problem.<\/p>\n However, for those who are really particular about meeting the specified values, I recommend preparing a cement slurry using local water and cement and performing on-site calibration.<\/p>\n Also, in standard cement slurry designs, ordinary cement is used.<\/p>\n As a result, the concentration of the cement slurry prepared using ordinary cement will differ.<\/p>\n Fast-setting cement is more concentrated because its particles are smaller.<\/p>\n <\/p>\n The standard value is 10 to 18 seconds; for ordinary cement, it will likely be closer to 10 seconds, while for high-early-strength cement, it may be closer to 14 seconds.<\/p>\n It's hard to say for sure, but that's a possibility. (Depending on the formulation.)<\/p>\n It also depends on the use of water-reducing agents.<\/p>\n Depending on the water-reducing agent, the setting time may be significantly faster or slower, so be sure to thoroughly understand the characteristics of the water-reducing agent you are using.<\/p>\n <\/p>\n Personally, I don't pay much attention to the quality measurements taken at P-Roto. (I do carry out the work, though.)<\/p>\n Especially when it's strong. Since the pump delivers it.<\/p>\n If the current is fast, all you have to do is try again.<\/p>\n <\/p>\n Some people get flustered during the observation period, but don't worry\u2014just try again.<\/p>\n That's fine. (Since it hasn't been used yet.)<\/p>\n To put it simply, as long as the concrete achieves the required strength, there is no problem, so please take great care to maintain the proper water-to-cement ratio (W\/C) during construction.<\/p>\n <\/p>\n See you later.<\/p>\n![\"Cement](\"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2016\/11\/c8aa13ed6d73f08d619b13dd520ad253.jpg\")
