Abstract: A process and method for solving the high need for a sustainable materials and good energy economy in the area of buildings and civil infrastructures in a value added and ecological way is described. The solution is a processing method and mix design of a recovered hydraulic composite material, starting from mixed construction or demolition wastes and ending into the hydraulic composite material. The raw materials of this recovery composite material comprise before adding water dominantly (90-100 mass %) recycling materials, which are processed at a concentrated plant. Waste is collected from mixed construction and demolition wastes on site and from selected byproducts of the industry. The share of construction or demolition wastes alone is more than 50 mass-% and more than 60 volume-% of the dry composite material mix. Harmful constituents are separated from the constituents of the composite in the waste treatment process. The density of the composite varies and can be specified through the mix recipe.

Abstract: Method and equipment for compacting of concrete mix when concrete products are being cast by means of a continuous method. The concrete mix is carried from the feeder device (4) forwards by means of an endless transfer unit. The compression required for the compacting of the concrete mix is produced by means of a roll (1) pressed against the transfer face (2). The compression is directed at the concrete mix by the intermediate of rigid plates (2) of a caterpillar band constituting the transfer unit, which plates are pressed against the concrete mix by means of two or more support rolls (1).
