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 polyolefinic films, of a net-like structure, containing, incorporated therein, 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. A process for preparing the fibrilled films and hydraulic binder-based manufactured products comprising them are also disclosed.
