Maximizer Concrete is a proprietary formula that yields more coverage than standard concrete mixes. Maximizer features a specially manufactured aggregate material and higher volume of cement. Maximizer Concrete has a strength of 5000 psi, is 40% stronger than regular concrete and yields 67% more coverage. Maximizer is more uniform, easy to mix and blend, and is air entrained to help prevent damage caused by winter's freeze-thaw cycles. It is great for posts, sidewalks, steps, balconies, benches, countertops and statues.
