Quikrete’s newest concrete mix balances working time and a fast cure for the best of both worlds, without sacrificing performance. Q-Max Pro offers one-hour working time, three-hour walk-on time (at 1,000 psi), and 6,500-psi compressive strength when fully cured. The combination lets contractors complete projects quickly while meeting requirements for both structural concrete use and concrete repair. Good for slabs, steps, floors, ramps, sidewalks, and patios, Q-Max Pro offers crack and freeze-thaw resistance. An 80-pound bag retails for less than $10. quikrete.com
