A: QUIKRETE® does not recommend placing concrete slabs at a 2” thickness, as this geometry does not provide strength or durability. Typical slab placements done with standard 2x4” lumber forms are 3-1/2” thick. At this thickness, each 10’ square slab will require 49 bags of 80-pounds each. Yields will vary with waste, uneven subgrade, etc.
A: Each 80-pound bag of QUIKRETE Concrete Mix yields approximately 0.6 cubic feet. For a 48" x 54" x 4" slab, you will need 6 cubic feet of concrete, or 10 80-pound bags. Yields are approximate and will vary with waste, uneven subgrades, etc.
A: QUIKRETE® Concrete Mix is a general utility concrete which achieves typical compressive strengths of 2,500 psi at 7 days and 4,000 psi at 28 days. Please consult a building official familiar with local building code to determine whether this is suitable for your application.
A: Landscaping stones can be pressed into fresh QUIKRETE® Concrete Mix to create an exposed-aggregate finish.
