Abstract
A measuring apparatus of submergence aggregate according to the present invention comprising a stock bin for storing fine aggregate, a fine aggregate feed hopper placed under the stock bin, a vibrating feeder placed under a discharge opening of the fine aggregate feed hopper, a screen device placed in the vicinity of an exit of the vibrating feeder, a measurement tank placed under the screen device, an electrode-type displacement sensor as means for measuring a water level placed above the measurement tank, and load cells as mass measuring means for measuring a mass of the measurement tank.
Claims14
An apparatus for measuring concrete-forming materials, comprising:
- aggregate supply means for supplying aggregate;
- water supply means for supplying water;
- a measurement tank for containing aggregate supplied from said aggregate supply means together with water supplied from said water supply means as submergence aggregate, with an opening for overflow in a wall of said measurement tank at a predetermined height thereof so that water in said measurement tank can overflow therefrom;
- a bottom lid attached at a bottom opening of said measurement tank, said bottom lid being movable for opening the bottom opening and closing the bottom opening in a water-tight manner;
- submergence aggregate mass measuring means for measuring a mass of the submergence aggregate in said measurement tank;
- and
- a vibrator above said measurement tank, said vibrator being free to move up and down such that said vibrator can be buried in the submergence aggregate.
