Lightweight concrete exhibits many advantages over traditional such as lower density and thermal conductivity an easier, cheaper, less energy-consuming manufacturing process. In order to extend its applications, there is a need study behavior in fire situations. Due that, the aim of this was assess resistance foam concrete, depending on thickness foaming process applied. Fire assessed according EN 1363-1. The results indicate usefulness terms isolating temperatures for discontinuous partition filling that are consequently real alternative dedicated solutions field passive protection. shown have large effect ability insulate with standard material preparation It also noted changing method continuous feeding may result achievement similar values while maintaining low density.
