Сomposition on the Basis of Fluorineanhydrite and Expanded Polystyrene for the Thermal Protection
Abstract:
The technogenic fluorineanhydrite is a waste product from the production of fluoric acid. It can have binding properties after its activation by some known chemical compounds, and so it may be used as a binder for the production of construction materials, in particular, the polystyrene concrete. The article considers the fluorineanhydrite composition as well as the polystyrene concrete produced on its basis with a surface-active additive and staple basalt fibre. The results of micro-structural and chemical analyses of developed composite are given. The polystyrene concrete (D 700 density class) has been developed with the ultimate compression strength value of 1.8 MPa and the water-resistance coefficient value of 0.68.
