Abstract

The paper presents the development of a Liapor lightweight concrete composite wall panel system through a specific industrial case study, based on the ongoing collaboration between Homes4You Készházak Ltd. and the University of Sopron within the framework of the Cooperative Doctoral Program, drawing on the experiences of the currently under-construction Mille-Ház project in Siófok. The study follows the development process from laboratory-scale material testing through full-scale (1:1) wall panel production to on-site assembly validation. The results confirmed the technical potential of the Liapor lightweight concrete composite material system; however, they also demonstrated that industrial applicability is not determined solely by thermal or mechanical performance parameters. Rather, it depends to a comparable extent on the system-level control of the tolerance chain, joint design, the constructability of lacing reinforcement, and the material homogeneity.
