Couldn't they just use recycled concrete (from broken up roads and buildings) or just rocks instead?

- VectorLock 8y agoPresumably they would need to build a vessel to hold the concrete rubble in, as opposed to casting their concrete directly in the shape they desire.
- CydeWeys 8y agoNo, the whole point is that they need to stack these blocks up very high. You need uniformly shaped blocks for this, so no rock, and recycling concrete doesn't let you reuse the cement as binding agent -- it's already inactivated. You just get to use reuse the aggregate, which isn't the environmentally expensive component to manufacture.
