ABSTRACT:
A method for casting of one concrete product or of several concrete products placed side by side at the same time by means of one casting machine as sliding casting out of high-consistency concrete mix. The concrete mix is fed by means of one feed member (2) or by means of several feed members placed side by side into one or several separate cross sections of a concrete product to be cast. The compacting of the concrete product or products to be cast is monitored by measuring the pressure of the concrete mix or the force arising from the pressure against a part (2; 9,7) of the casting machine in at least two points of the cross section and by separately regulating the operating values of at least two parallel feed member (2) or of the compacting movements of at least two parallel compacting members (3) on the basis of the measurement values obtained.
