Concrete lovers, today we're diving into the world of C30 concrete! 🏗️ If you're wondering about its slump (塌落度), let's break it down. The slump value for C30 concrete typically ranges from 70 to 90 millimeters. This measurement tells us how fluid the concrete is and how well it can be poured into forms. 😊 A higher slump means more flowability, which is great for intricate designs but needs careful handling to avoid segregation.

C30 concrete is widely used in construction projects like bridges, buildings, and pavements due to its excellent strength and durability. 💪 When mixed properly, it offers consistent performance under various conditions. Remember, the slump test is simple but crucial. It involves placing the concrete in a slump cone and measuring how much it settles after being lifted. 📏

So next time you're working with C30, keep an eye on that slump value—it’s your key to perfect pours every time! 🎯
