Abstract
A process for the manufacture of concrete construction parts with a binder, for example cement, inorganic aggregates, for example sand and an addition of foamed synthetic material, for example foamed polystyrene, in which a granulate of synthetic material is introduced into a Concrete mixer made in the form of a pressure vessel and, feeding steam, the granulate expands in it for a time of 2 to 8 minutes at a pressure between 0.1 to 1 atmospheres gauge and at a temperature of saturated steam, the expansion being carried out before and/or during the process of mixing the synthetic material granules with a binder, inorganic aggregate and water and controlling the expansion so that the bulk densities of the granules between 10 and 20 kg/m3 are reached, and the proportions of the components of the mixture in such a way that the amount of granulate amounts to 20 to 70% by volume, the amount of aggregate to 5 up to 50% by volume, the amount of binder at 10 to 35% by volume and the amount of water at 5 to 20% by volume, based on the volume of the concrete formulation prepared per cubic meter; and once the mixing process is complete, the product resulting from the mixture is fed to a mold and compacted from the outside using a pressure, for example by means of a pressing tap, while the synthetic material granules are in the finished foaming state, but still plastic.
