Fibrillated and orientated reinforcement films made of at least one film-forming, orientable synthetic polymer, process for the preparation of such films and hydraulic binder-based products containing these films

摘要

Fibrilled polyolefinicfilms, of a net-like structure, containing incorporated from 1 %to 20% by weight of a cement-based material, are used as a reinforcement in the preparation of manufactured products based on hydraulic binders.
