Modifikuotas mažacementis kaitrai atsparus betonas su aliuminatiniu cementu ir šamoto užpildais

Abstract

The possibilities to improve the qualities of refractory castable with porous chamotte aggregates and aluminate cement with - 40% of Al2O3 were investigated. In order to choose the optimal particle size distribution Andreassen wquation was used. The rheological properties of pastes and main [hysical-mechanical oroperties of concrete after firing at various temperatures were determined.
