各种指标有助于确定混凝土裂缝的严重程度。假设混凝土裂缝是严重的，如果它们连续活跃和加宽，则允许水分渗透，保持污垢，或位于高可见区域中。结构裂缝可以影响力量和durability of structural concrete.
裂缝的严重程度可以从一个结构变化到另一个结构。此外，监督工作的人的角度同样重要。例如，承包商或工程师可以接受特定的裂缝宽度，但是建筑物乘客可能是不可接受的。
So, there is no clear line to determine the seriousness of concrete crack, and it should be ascertained based on the specifications and requirements of the project under consideration.
如何确定混凝土裂缝的严重程度？
- Generally, cracks with a width of less than 0.3 mm are acceptable and do not affect the structure. However, they may develop and grow to become structural cracks. Therefore, one should monitor small cracks on houses or structures.
- Crack width greater than 0.3 mm can create problems for the durability of the structure.
- If the crack is static, then it is not severe. However, as theconcrete crack逐渐扩大,它最终将成为一个structural crack and cause structural problems, unless the crack is repaired.
- When cracks on a horizontal concrete surface such as a concrete slab get widened to a degree of causing a tripping hazard, it is considered a severe crack and needs immediate repair.
- 如果裂缝捕获污垢并导致卫生或维护问题，则被认为是一个严重的裂缝。
- Cracks on slabs and foundation walls that permit the moisture seepage are severe and need suitable treatment.
- The maximum allowable基础上的裂缝宽度is nearly 3.2 mm. Damping and watertight agents can bridge a crack width of 3.2 mm.
- 最好修复位于混凝土结构的高可见性区域的裂缝。
- Short and, sometimes, vertical hairline cracks on the foundation wall would not cause structural problems.
- Long diagonal cracks on basement walls are a sign of overstressing of the basement wall. Frequently, cracks caused by overstressing originate from the upper corner of the foundation wall.
- Mostly,基金会结算是原因of the long diagonal cracks on the basement walls. So, it requires immediate action to tackle the problem. One may notice signs offoundation settlement在堵塞门和窗的上层结构中。
- 在混凝土放置范围内出现的裂缝是塑料收缩裂缝或塑料沉降裂缝。宽度plastic and shrinkage cracksranges from 1 mm to 2 mm; cracks with greater widths shall be repaired on priority. Segregation and bleeding of concrete are the causes of such types of cracks.
FAQs
Structural cracks result from incorrect design, faulty construction, or overloading, which may endanger a building's safety and its occupants. Please read morehere.
非结构裂缝主要是由于建筑材料内部诱导的应力。这些裂缝通常不会危及安全性，但可能看起来难看，产生错误的工作印象，或者给出不稳定的感觉。请阅读更多here.
基础上的最大允许裂缝宽度近3.2毫米。阻尼和防水剂可以桥接裂缝宽度为3.2毫米。
混凝土中的主动裂缝是活裂缝，其长度，宽度和深度随时间扩展。由于过载和热膨胀，因此形成了这些裂缝。由于冻融引起的裂缝。
各种指标有助于确定混凝土裂缝的严重程度。The concrete cracks are assumed to be serious if they are active and continuously widening, allow moisture penetration, retain dirt, or are located in a high visibility area. The structural cracks can influence both strength and durability of structural concrete
