Abstract

On peut obtenir des pierres, notamment de béton, de poids spécifique brut et de dimensions constantes en mesurant la hauteur des pierres et leur poids. On change le degré de remplissage d'après les écarts entre valeurs mesurées et valeurs de consigne. Pour éliminer l'influence de la hauteur des planches, on palpe la surface des pierres et celle des planches et on fait la différence des hauteurs. Dans la mesure des poids, on soustrait le poids connu des planches du poids total des planches et des pierres.Stones, especially concrete, of gross specific gravity and constant dimensions can be obtained by measuring the height of the stones and their weight. The degree of filling is changed according to the differences between the measured values and the set values. To eliminate the influence of the height of the planks, the surface of the stones and that of the planks are palpated and the height is differentiated. In the weight measurement, the known weight of the boards is subtracted from the total weight of the boards and stones.
