Big Screed - Concrete rapid vertical slip-forming with SpaceCrete

https://spacecrete.com/ One application of spacecrete, where rough excavated walls are concreted over. The state-of-the-art methods, and a big screed with automated placement of spacecrete. Since we don't yet have the resources to build this, we are starting with animation. The concrete placement system is on a carriage. It includes an inline mixer where the concrete is intermixed with a thickening admixture, and a "mudulator" that smooths out the pulses from a swing-tube piston pump (detailed in the next video).
