Abstract: This report reviews existing literature to determine if a minimum allowable concrete strength can be established for portland cement concrete pavements and floor slabs. The range of concrete strengths shown on existing Corps of Engineers design charts for concrete pavements and floor slabs represents only a reasonable range of strengths, and lower-strength concrete may be used if the pavement and floor slab thickness are increased appropriately to ensure structural adequacy. However, a reduction in concrete strength will reduce the abrasion resistance of the concrete surface. Minimum strengths for warehouse and similar heavily loaded slabs are recommended for adoption in Army TM 5-809-12, "Concrete Floor Slabs on Grade Subjected to Heavy Loads," to ensure adequate abrasion resistance. These minimum strengths are drawn from current recommended practice in the U.S. Abrasion has not been a problem with concrete pavements so a recommended minimum strength is not justified at the present time.
