A Comprehensive Study of the Polypropylene Fiber ...

Jan 25, 2016  As a cementitious material, geopolymers show a high quasi-brittle behavior and a relatively low fracture energy. To overcome such a weakness, incorporation of fibers to a brittle matrix is a well-known technique to enhance the flexural properties. This study comprehensively evaluates the short and long term impacts of different volume percentages of polypropylene fiber (PPF) reinforcement

Geopolymers (natural building forum at permies)

There was one paper that argued that cob gets some of its strength from geopolymers in it. The theory was the clay is allowing slight decomposition of the fibers with biological interaction and then in that humic acid environment silica alumina bonds are forming giving the cob greater structure and strength. Who knows, it could be true.
