Recycled Aggregate 0-3mm. This is a fine aggregate produced through a multi-stage cleaning and cleansing process. 0-3 mm Recycled Aggregate is completely recycled. It is suited for use as raw material and applied as a mix with the coarse structure to complete the grading. Its cementitious residual base allows for better bonding and final grading.
