for holding the pads firmly in place while an additional series of dividing channels secures each pad also to the floor to delineate elongated segments between channels and wherein air pockets may form as pressurized air is directed underneath the pads with the perviousness of the pads allowing the air to effect shifting of this cementitious material towards the arranged lower conveying trough for discharge application_number US 15234580 A description in referring to the drawings and in particular fig1 there is shown an opened barge 1 which has been constructed for use for the purposes of this invention and that is incorporating the inclined structured floors 2 having a series of aeration pads 3 of this invention secured thereupon arranged intermediate these floors and pads are the flow troughs 4 which after the cement has been turbulently forced by means of pressurized air to flow by way of gravity down the incline of the barge floors enters into these troughs and is moved by air slides to flow towards central locations as at 5 where the cement is evacuated through discharge pipes by pumps for transfer to other locations normally on land for storage generally the barges are constructed into two segments that being the segments 6 and 7 as shown each of these segments is formed having at least four of the structured floors and accompanying air pads of this invention arranged in converging formations with.
