Aggregate exposing machine |
摘要 |
A machine for removing uncured concrete from the top surface of a cast concrete slab to expose the aggregate therein to provide a decorative surface finish. The machine utilizes a pair of counter-rotating brushes to remove concrete which has been prevented from setting by use of a surface retarder, thereby exposing the aggregate to leave an attractive exposed aggregate finish. The counter-rotating brushes deposit the uncured concrete brushed from the surface of the slab onto a conveyor which carries the concrete waste to the edge of the slab for disposal.
