Sidney, I assume you are referring to a "Design" crack width limitation. If so, ACI 224R, "Control of Cracking", provides guidelines in their TABLE 4.1, Tolerable Crack Widths. For moist air and soil they recommend a limit of 0.012 inch. If your structures will be susceptible to deicing salts or similar chemicals they recommend 0.007 inch. If you are going to specify a design crack width limit then I would suggest you also specify that the crack width be calculated in accordance with ACI 318 section R10.6.4. Note that the above crack limits correspond to a "z" value of 131 and 77 respectively which is another way of specifying crack limits. Thomas Hunt TOM.HUNT(--nospam--at)fluordaniel.com ...
