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 ...
The building is leaning toward the northwest, [30] [31] [32] and this has caused cracks in the building's basement and the pavement surrounding the tower. [33] As of 2018, the sinking had increased to 18 inches (46 cm) with a lean of 14 inches (36 cm). [34] Measurements in 2022 show the tilt increased to 28 inches (71 cm), as measured from the ...
A building collapse due to sinking is likely only if parts are sinking at different rates, creating tensions that weaken the structure, known as differential settlement. The researchers noted that other overbuilt areas were sinking at a significantly faster rate, such as on the artificial islands in Biscayne Bay – up to 3.8 mm (0.15 in) per year.

Typical crack pattern of the alkali-silica reaction (ASR). The gel exudations through the concrete cracks have a characteristic yellow color and a high pH. The fatty aspect of the exudations imbibing the concrete porosity along the cracks is also a distinctive feature of ASR. The alkali-silica reaction as a chemical cycle process
