<p>PURPOSE:To reuse concrete waste taken into pieces for regenerated cement, fine aggregate of concrete, etc., by grinding concrete waste taken into pieces and separating to give a hardened material of cement, pulverizing the pulverized material and activating unhydrated cement. CONSTITUTION:A deteriorated building structure is taken into pieces to give concrete waste, which is ground by a crusher and separated into an aggregate and a hardened material of cement. The hardened material of cement is further ground by a pulverizer and unhydrated part not undergoing hydration reaction as cement is regenerated and exposed. The pulverized cement is used for regenerated cement or fine aggregate of concrete.</p> |
