THE PROPERTIES OF A LOW CEMENT CASTABLE CONTAINING

The properties of such kind of castables were com-pared in respect of the increase of both the concentra-tion of the gel mass and firing temperatures. Apparent porosity (AP) bulk density (BD) and cold crushing strength (CCS) of the castables were determined by the standard methods reported earlier 18-24 . The IR traces

Ceramic Castables — Final Stage in the Evolution of Low

Abstract. Technological and service characteristics of ceramic castables and low-cement refractory castables (LCRCs) are compared. Unlike LCRCs prepared from dry-ground powders the ceramic castables contain a nanoparticle phase (5100 nm) which to a significant extent determines their operational properties.
