As mentioned previously mentioned, concrete is rather strong in compression, but weak in stress. More substantial earthquakes can crank out incredibly substantial shear masses on buildings. These shear loads matter the structure to both of those tensile and compressional hundreds. Concrete structures without reinforcement, like other unreinforced masonry structures, can fail throughout extreme earthquake shaking.
Inside the shell from the mixer drum can be a set of blades or fins that wrap in the helical (spiral) configuration from the head for the opening from the drum. This configuration allows the concrete To combine when the drum spins in one path and causes it to discharge if the direction is reversed.
