Aggregates. The two most important factors when producing construction aggregate is shape and maximum yield of highest value product. Every successful aggregate producer can achieve both with the right raw materials, the right equipment, the right flow sheet and the right operation of equipment.

One top-surface retarder product is Surface Deactivator by Brickform, which provides ten exposure depths, from a simulated light acid etch or sand blast finish up to full exposure of 1 ½" aggregate. Surface Deactivator offers an extended window before the surface paste is removed, allowing the concrete to harden properly, which locks in the aggregate and decreases pop-outs.
