Weathering may require a higher strength concrete or grade of masonry <br />than necessary to satisfy the structural requirements of this code. The <br />weathering column shall be filled in with the weathering index (i.e., "negligible," <br />"moderate" or "severe") for concrete as determined from the Weathering <br />Probability Map [Figure R301.2(3)].
