METHOD FOR TREATING RESIDUAL READY-MIXED CONCRETE AND APPARATUS THEREFOR

PURPOSE:To obtain square cakes having a high compressive strength by dehydrating a sludge without storing thereof in a storage tank for a long period, taking out the resultant dehydrated cakes from filter plates and sprinkling a specific powdery substance thereon. CONSTITUTION:This method for treating the residual ready-mixed concrete is to dehydrate a sludge obtained by separating an aggregate from wash water used for washing the return ready-mixed concrete or a concrete mixer truck with a filter press 1 without storing thereof in a storage tank for a long period, then retreat a movable plate 17, drop the resultant dehydrated cake 16 downward, bring the dropped dehydrated cake into contact with a tilted cake receiving plate 3, lay down the dehydrated cake, stop the laid down dehydrated cake with a stopper 11, subsequently make a receiving plate 3 horizontal with an elevating ram 10, simultaneously lower the dehydrated cake onto a turntable 2 with a cake lifting and lowering ram 9, sprinkle a powdery substance such as cake powder or stone dust on the dehydrated cake 16, place each dehydrated cake into a multilayered form, cure the prepared dehydrated cakes for a prescribed time, then cut the cured dehydrated cakes 16 into a square form with a cutter 5 of a cutting machine 4 and store the produced crushed cakes in a storage truck 6.
