Cinderblocks

Cinderblocks are the lego brick of informal urban space. They empower anyone to build shelter.

Problems

Supply-side

Cinderblocks are made from cast concrete, (Portland cement and aggregate). Usually sand and fine gravel for high-density blocks. Low-density blocks often use industrial wastes as an aggregate. Lightweight blocks can be produced using aerated concrete.

Ideas and Possibilities

Can we build a better cinderblock? To improve on the current design, some desirable properties:

Can we re-think the process?

Could one make something like Glass Fiber Reinforced Concrete using mud, recycled plastics or other readily available materials?
