Ceramic Recycled Aggregate
Recycled aggregates for construction that enhance the strength and durability of materials along with harmless treatment of harmful substances such as heavy metals by ceramic treatment of the mixture of incineration ash with inorganic sludge(10-20%) in a high temperature molten state using a kiln.
Ceramic recycled aggregate can be used as an alternative material for aggregates in ready mixed concrete, and for fine aggregates to manufacture various concrete products such as bricks and blocks. It can also be used as a base material for road construction, backfill materials for underground work and etc.

Harmless / Stabilization Treatment
​
In a high temperature using a kiln, heavy metals in incineration ash(bottom and fly ash) with inorganic sludge are solidified and stabilized, so it drastically reduces the outflow of heavy metals into the environment.
As a result of the TCLP test, the amount of heavy metals discharged is measured far below the environmental permissible standard, and thus, it was confirmed that the possibility of environmental pollution was very low.

Enhancement of the strength of product
​
The strength of the ceramic recycled aggregate is remarkably enhanced by firing the mixture of the incineration ash(bottom ash and fly ash) with inorganic sludge at a high temperature.
​
The strength level (avg. 32.6 MPa) of ceramic recycled aggregates significantly exceeds the aggregate quality standard (28.0 MPa) and can be used as an alternative material for manufacturing various concrete products such as bricks and blocks as well as aggregates for ready-mixed concrete.
