Thermally and acoustically insulating, water-repellent, fire resistant, slab-shaped building components are formed by wetting a plurality of expanded polystyrene beads with water and water-soluble synthetic resin, to coat the beads adding an inert filler drying and/or polymerizing the resin and mixing the thus-coated beads with predetermined proportions of cement, sand, fluidifying additive and water and also stearate. The thus-obtained mixture is put into a slab-shaped form and reinforcing components are immersed in the form. The mixture is cured and a thus-formed slab-shaped element is withdrawn from the form.
