Реферат: Material comprises 50-75 vol. % of microspheres of oxides with a m. pt. >1700 degrees C. The microspheres have dia. 10-200 mu and are sintered to each other so that their dia. of contact is 0.2-0.5 of the microsphere dia. Material has increased compression and tensile strength, higher deformability and higher recrystallisation resistance than known heat-resistant materials. In an example, microspheres of ZrO2 stabilised by CaO were vibration moulded and sintered to produce a heat resistant material of compression strength 2000 Kg/cm2.
Geo-polymer binding system for heat-resistant concretes, the binding system containing dry heat-resistant concrete mixture, and also the mixtures application
