R-Value of Concrete Concrete Construction Magazine

Mar 01, 1995  The R-value of an uninsulated, 8-inch-thick basement wall built using normal-weight concrete is 1.35, based on data from the 1993 American Society of Heating, Refrigeration, and Air-Conditioning Engineers' Handbook. By doubling the thickness of the wall to 16 inches, the R-value only increases by 0.50.

DENSITY-RELATED PROPERTIES OF CONCRETE MASONRY

The fire resistance of concrete masonry walls depends on the geometry of the concrete masonry units, and the density of the concrete block. The unit geometry affects the effective or “equivalent” unit thickness. For a given unit configuration, the fire resistance of a concrete masonry wall increases as the concrete density decreases.
