| description | A control method for charging ready-mixed concrete additives batchwise which aims at keeping the slump of ready-mixed concrete within a certain range and making longer transportation by truck mixer possible without degrading the quality, where the slump of ready-mixed concrete is detected electrically as a change in the mixing torque so that, when this detected value reaches a value set beforehand, a motor receives a control instruction to charge additives for adjusting slump into the ready-mixed concrete and so that the operating time of the motor for charging additives and the interval until control operation is reset may be adjusted with a timer. |
