Magnesium oxychloride cement-based composite with foam glass used as lightweigth admixture

Popis výsledku v původním jazyce

In this paper, foam glass was used as an aggregate in magnesium oxychloride cement (MOC) based mixtures. Magnesium oxychloride cement is known as a non-hydraulic, high strength, and fire resistant binder that is able to bond large amount of miscellaneous fillers. In comparison with Portland cement, MOC has lower environmental impact over its whole life cycle. The purpose of this paper is to modify thermal and hygric properties of MOC composites using lightweight mineral admixture, namely foam glass, and hydrophobic agents. The raw materials were by XRF spectroscopy and basic properties characterised. The MOC composites were also by their basic material properties, strength parameters, thermal conductivity, volumetric heat capacity, and water transport properties described. The results show significantly improved thermal parameters of MOC composite containing foam glass as aggregate and indicate high efficiency of surface hydrophobic agent as a barrier against the transport of liquid moisture. The resulting lightweight MOC composite with improved thermal insulation and suitable mechanical properties can be used to produce thermal insulation floors, ceiling or wall panels reducing the energy performance of buildings.
