That\u2019s exactly why the construction company is willing to work with him, isn\u2019t it?<\/strong><\/span><\/p>\n <\/p>\n And usually, those kinds of people who try to knock others down say something like this:<\/p>\n Like, \"Once I get promoted, I'll bring you up with me\"... lol<\/strong><\/span><\/p>\n But that's beside the point.<\/p>\n Do you use different types of cement slurry in summer and winter?<\/span>Are you doing that?<\/p>\n I do vary my approach slightly, depending on the timing and project schedule.<\/p>\n 1. When there is no construction schedule = Rapid-setting cement<\/strong><\/span><\/p>\n 2. When there is a construction schedule = Ordinary cement (e.g., reverse-wrap method)<\/strong><\/span><\/p>\n 3. Cold Weather = Early-Strength Cement<\/strong><\/span><\/p>\n 4. When it's hot = Regular cement (has a margin of safety for tensile strength testing)<\/strong><\/span><\/p>\n 5. When the injection distance is long = ordinary cement<\/strong><\/span><\/p>\n 6. When the injection distance is short = Either way<\/strong><\/span><\/p>\n That's the gist of it.<\/p>\n The general perception is that when there\u2019s a tight schedule, it\u2019s hot, and the distance is long, cement is usually the go-to choice.<\/p>\n When mixed with ordinary cement, the milk concentration is lower, so the flow rate increases.<\/p>\n That means it's suitable for long distances.<\/p>\n When used in cold weather, fast-setting cement hardens quickly due to its high heat of hydration, resulting in early strength.<\/p>\n Furthermore, fast-setting cement generally has low workability and a slow flow rate.<\/p>\n Naturally, the injection costs will go up.<\/p>\n Cement costs will rise by about 20 percent, but<\/p>\n The construction period from the start of grouting work to the start of service will be significantly shortened to nearly half.<\/p>\n I think you'll immediately see which is more cost-effective when you compare the labor costs to the cement costs.<\/p>\n <\/p>\n See you later.<\/p>","protected":false},"excerpt":{"rendered":" Hello, everyone.
