MANUFACTURING METHOD OF RECYCLED AGGREGATE FROM DUST OF WASTE CONCRETE AND RECYCLED AGGREGATE PRODUCED THEREFROM

摘要

The present invention is a method for producing recycled aggregates that can be used in construction sites by molding the fine powder generated in the waste concrete crushing / classification process into a molded body at room temperature and then using a modified sulfur coating solution and the recycled aggregate produced therefrom It is about. More specifically, the method of the present invention comprises the steps of providing the waste concrete fine powder, molding the fine powder and cement mixture into a spherical or pellet form at room temperature, drying the molded molded body and using the modified sulfur coating solution Coating the dried formed body.;According to the present invention, by forming and coating the waste fine powder generated from the waste concrete at room temperature, it is possible to produce recycled aggregates having excellent physical properties that can be used again in construction sites, so that the effect of recycling waste resources and minimizing environmental pollution can be expected. have.
