Method includes laying raw mix in mould, its compaction and heating. Layer of mix heated below binder melt temperature is laid in mould, reinforcement net of high-strength threads is laid over, the second layer of mixture is applied and exposed to hot pressing. ^ EFFECT: reduced duration of sheets manufacturing, exclusion of carcinogenic substance - asbestos and expensive low-quality binder - cement from mix composition, substitution of deficit cement with domestic and industrial wastes of polyethylene, increased flexural strength. ^ 2 cl, 1 tbl</p> |
