发明名称 Method for fabricating a concrete product
摘要 A method is provided are for fabricating a concrete product in a substantially horizontal slip-form casting process, in which method concrete mix is fed into a slip-form mold of a defined cross section moving progressively in the casting process so as to give a concrete product of a desired shape. The input power need of the concrete mix feed and compaction is measured, whereupon the travel resistance of the casting machine is controlled based on the value of a measured process variable. Therefore, quality variations in a slip-form cast product that are caused by changes in the density of the concrete mix and the travel resistance of the casting machine are eliminated.
