Gonchar V. Abrasive and thermoresistant composite materials based on alkaline aluminosilicate binders.

Composite materials based on alkaline aluminosilicate binders. To theoretically substantiate and practically confirm the possibility of producing composite materials, which characterised high abrasive- and thetmoresistant,. These materials may be made in a system Na2O-Al2O3-SiO2-H2O by directional synthesis in composition of hydration products of zeolite-like new formation with high thermostability. The fields of crystallisation are established and the requirements for synthesis of thermostable zeolites are determined. The proposed composite materials are characterised by: compressive strength -55-60MPa, abradability - 0,25 - 0,44 g per sq cm, thermoresistance - 75-80 cycles "8000С - water". The range of application - building.
