building scraps mainly refer to sludge generated during the construction of foundation works, such as reverse circulation piles, diaphragm wall, pre-packed piles in row and pebble grinding. Through granulation and solidification, such scraps can be reused in base backfill or stable layer. The solidification technique is used to change inorganic sludge and limestone powder into modified soil particle, which are then crushed into aggregates after forming by pressure. We can provide complete auxiliary recycling and processing equipment for building waste. Meanwhile, We can also supply a full set of recycling equipment and technique for scraps particle to dispose the sludge and waste soil. With respect to the innovative scraps recycling equipment and techniques, the solidification technique is such technique that can be used to change building scraps and power into improved soil and recycled aggregates.
