Settlement cracks usually show up as vertical lines or hairline cracks (small cracks that are under 1/10 of an inch or 2.5 millimeters wide), especially around weak spots like doors, windows, and ...
Cracked walls: Cracks may be horizontal, vertical, diagonal or stair-stepped. Severe pressure or structural damage is evident by widening cracks. Buckling walls: Usually caused by hydrostatic pressure. Walls appear to be bowed inward. Peeling paint: Water seeping through walls may lead to bubbling or peeling paint along basement walls. [4]
Oxide jacking has caused concrete spalling on walls of the Herbst Pavilion at Fort Mason Center in San Francisco. The expansive force of rusting, which may be called oxide jacking or rust burst, is a phenomenon that can cause damage to structures made of stone, masonry, concrete or ceramics, and reinforced with metal components.
An unrendered 9-in. wall is regarded as substandard."

Cracks development occurs when early-age concrete is insufficiently protected against desiccation and too much water evaporates with heat because of unfavorable meteorological conditions: e.g, high temperature, direct solar insolation, dry air, low relative humidity, and high wind speed during summer, or in hot conditions. Curing is intended to ...
There are several other processes that can lead to intergranular fracture or preferential crack propagation at the grain boundaries: [8] [6] Microvoid nucleation and coalescence at inclusions or second phase particles located along grain boundaries; Grain boundary crack and cavity formations associated with elevated temperature stress rupture ...
