Acceptable concrete cracking
A. Concrete cracks are possible on any project, so it’s wise to set reasonable expectations for yours. Foundation walls are normally designed as reinforced concrete. Reasonable crack widths for reinforced concrete under service loads are listed in Table 4.1 of ACI 224R-01.
Do we always need to repair cracked concrete? - American …
A. Cracks in concrete have many causes and effects. The cracks may affect appearance only, or they may indicate significant structural distress or a lack of resistance to degradation in the environment of service (ACI 224.1R). Cracks may represent the total extent of the damage, or they may point to problems of greater magnitude.
small cracks in lieu of a fewer number of larger cracks. It is unrealistic to expect crack-free floors. Every owner should be advised…” • This is “normal” expected performance. What if that is not acceptable?

Analysis of Compressive Stress-Induced Cracks in Concrete
Sep 1, 1998 · Cracks and pores in the concrete specimens were impregnated with an alloy that has low melting point. At the stress of interest, this alloy was solidified to preserve the stress-induced microcracks as they exist under load and images from the cross sections of the concrete specimens were obtained using Scanning Electron Microscopy (SEM).
