Maximizer Concrete from Sakrete is a manufactured aggregate material designed with a proprietary formula that yields a higher volume of cement (67% more coverage) than standard concrete mixes. An 80-lb. bag yields one full cubic foot with 5,500-per-square-inch strength 28 days after being poured; a 40-lb. bag is also available. Maximizer Concrete is suited for countertops, posts, sidewalks, steps, balconies, benches, and statues. It is air entrained for improved freeze-thaw resistance, exceeds applicable provisions of ASTM C387, and features a more uniform, easy-to-mix blend. It requires minimum 2"-thick placement.
