Crack widths close the reinforcement [PDF]
IABSE Reports, 2007 <p>Currently used design methods predict that the crack widths at the concrete surface increase significantly with concrete cover. Requirements concerning limitation of crack widths therefore makes it difficult to use large concrete covers, which otherwise is desirable to reduce the corrosion of reinforcement.

Probability-Based Crack Width Estimation Model for Flexural Members of Underground RC Box Culverts
Applied Sciences, 2022 Crack control for slabs and beams in current design practices in Korea are based on the Frosch’s model, which is adapted in ACI 318. It is more difficult to have consistent quality control in underground construction sites, such as the RC box culverts ...
