Background technology
Form caused by crack and species are a lot, there is the reason for design aspect, but be more work progress it is various because
Caused by element combination, to solve crack problem in concrete at all, it is desired nonetheless to from the Crack cause human hand of distress in concrete.Just
Really judge and the origin cause of formation of analysis distress in concrete is to efficiently control and reduce maximally effective approach caused by distress in concrete.
Contraction is a key property of concrete, is had a significant impact to the performance of concrete.It is caused due to contraction
Micro crack once develops, it is likely that causes cracking, deformation or even the destruction of works.The reason for producing contraction fissure, one
As think the construction stage because the effect of hydration heat of cement and outside air temperature causes concrete shrinkage and caused by crack.Mostly advise
Strip then, seldom intersect.Often occur at structure variable cross-section, it is often parallel with steel bar stress.Contraction fissure mostly occurs big
In volume concrete, the small blocks component such as beam, plate, post, prestressed component seldom produces contraction fissure.Concrete shrinkage crack is endangered
Evil is larger, especially the structures of exposure in an atmosphere, influences bigger.Such as it is not added with, to prevent, being likely to result in serious consequence.
The influence of frost, this is more severe in the performance of northern area;Concrete once produces crack, and moisture will multiply
Empty and enter, even if it is not very deep to penetrate into, but when outside air temperature is dropped to less than -2 °C, moisture will congeal into ice, moisture icing
Volumetric expansion about 9% afterwards, cause the spallation of edge of crack, and ice melts this spallation of circulation primary and just occurred once, so, crack
To gradually it widen.In addition, crack Producing reason is caused to also have others etc. factor.
