It is concluded that more research into the use of explosives and bursting techniques for partial demolition of both reinforced and prestressed concrete members could lead to considerable savings in time and reductions in demolition costs.
Chemical Demolition — Another unique solution from ATI. This cuttingedge approach is made possible by a chemical powder that releases an impressive 18,000 PSI of expansive strength when mixed with water. The agent is poured into drilled holes and begins to work silently, fracturing concrete and stone into manageable sizes and shapes.
Aggregates concrete. Concrete aggregate collected from demolition sites is put through a crushing machine, often along with asphalt, bricks, dirt, and rocks. Smaller pieces of concrete are used as gravel for new construction projects. Crushed recycled concrete can also be used as the dry aggregate for brand new concrete if it is free of contaminants.
