Lime stucco has the property of being self-healing to a limited degree because of the slight water solubility of lime (which in solution can be deposited in cracks, where it solidifies). Portland cement stucco is very hard and brittle and can easily crack and separate from the surface if the base on which it is applied is not stable.
Another topic might be how to address "wounds" in the stucco from furnature movers and high power sprayers. —The preceding unsigned comment was added by 71.198.120.221 20:43, 4 March 2007 (UTC). If the cracks are hairline, don't worry about them. If they're bigger, there is material made especially for repairing stucco cracks.
Stress corrosion cracking (SCC) is the growth of crack formation in a corrosive environment. It can lead to unexpected and sudden failure of normally ductile metal alloys subjected to a tensile stress, especially at elevated temperature. SCC is highly chemically specific in that certain alloys are likely to undergo SCC only when exposed to a ...
Crack growth, as shown by fracture mechanics, is exponential in nature; meaning that the crack growth rate is a function of an exponent of the current crack size (see Paris' law). This means that only the largest cracks influence the overall strength of a structure; small internal damages do not necessarily decrease the strength.
Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials. It uses methods of analytical solid mechanics to calculate the driving force on a crack and those of experimental solid mechanics to characterize the material's resistance to fracture.
Quench cracking, or crack growth following a quenching process, is another example of intergranular fracture and almost always occurs by intergranular processes. [6] This process of quench cracking is promoted by weakened grain boundaries and large grain sizes and additionally influenced by the temperature gradient at which quenching occurs and ...
A common example is one-coat stucco, which is a thick, synthetic stucco applied in a single layer (traditional stucco is applied in 3 layers). EIFS are proprietary systems of a particular EIFS manufacturer and consist of specific components. EIFS are not generic products made from common separate materials. The materials and installation ...
Fracture toughness varies by approximately 4 orders of magnitude across materials. Metals hold the highest values of fracture toughness. Cracks cannot easily propagate in tough materials, making metals highly resistant to cracking under stress and gives their stress–strain curve a large zone of plastic flow.
