You could learn a lot from youtube videos too. There's this lady on this one video she's in like, arazona or california or something and she has this house she is like building it out of papercrete. Its cooooool.

Its generally used as poured walls, cast into blocks, or drained & daubed onto metal framework. Papercrete can be used as mortar between papercrete blocks.

The lime content in the cement rotproofs the paper, so this property might (I've not tested it) be compromised by addition of pozzolans. A fairly wide range of different waste & raw material streams can be added to papercrete, they do modify the properties of course.

My own testing showed that compressing the material in the mould made a big improvement in compressive strength, and enabled immediate demoulding.

It bends slightly before it fails completely, making it possible to embed glass in it, as ASR doesn't cause failure. This property also makes papercrete bulletproof, and means that screws can be screwed straight in to it. Nailing doesn't work.

This new technology for construction is very interesting and it also helps in the advancement of green technology. I'm currently running a company that is into scrap paper trading. Most of our papers are shipped to paper mills for paper recycling. Using paper fibers as an ingredient for making concrete is a new technology here in the philippines.

What additives are placed to make papercrete fire-resistant and will it stand in a tropical country like ours?
