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



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?
