Structural cracks often show up as horizontal cracks, have stair-step patterns, or have wide, uneven openings. Diagonal cracks that run at a 45-degree angle can also indicate structural problems ...
Cracks: Cracks in the home’s interior sheetrock, chimney, tiles or home exterior can mean the foundation is cracked, especially if the cracks are horizontal or zig zagged. If the cracks grow or ...
Cracks appear in the concrete cover protecting the rebar against corrosion and constitute preferential pathways for CO 2 direct ingress towards the rebar. This accelerates the carbonation reaction and in turn the corrosion process speeds up. This explain why the carbonation reaction of reinforced concrete is an undesirable process in concrete ...
This movement compresses the foundation, often creating cracks on the concrete. This weakens the structure. Another byproduct of the heat is it can cause a foundation to sink to the ground.
Collapsed barn at Hörsne, Gotland, Sweden Building collapse due to snow weight. Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs.
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 ...
Frost damage can occur as cracks, stone splinters and swelling of the material. When water freezes, the volume of water increases by 9 %. [citation needed] When the volumetric moisture content exceeds 91 %, then the volume increase of water in the pores of the material caused by freezing cannot be absorbed by sufficient empty pores. This causes ...
The sharp corner at the brick has acted as a stress concentrator within the concrete causing it to crack. The de Havilland Comet aircraft experienced a number of catastrophic failures that were eventually found to be due to fatigue cracks growing from the high stress concentration caused by the use of punched rivet holes around the windows. The ...
