Background technology
Concrete shrinkage refers to that concrete hardens and during military service in condensation, and owing to internal moisture changes, temperature becomes
Reducing of the volume that the factors such as change and chemical reaction cause.The contraction distortion behavior of concrete mainly includes pouring
Plastic set contraction, self-constriction, dry shrinkage, temperature deformation and the Carbonization contract at initial stage.Concrete shrinkage and opening of causing thereof
Splitting is one of principal element affecting volume stability of concrete and structure durability, along with the high performance concrete of low water binder ratio
Obtaining continuous popularization and application in engineering, civil engineering field pays much attention to the concrete cracking phenomenon caused due to contraction especially.
Highlands is dry, and ambient humidity is low, and xoncrete structure is highly susceptible to such environmental effects in early days to be caused
Its contraction is greatly improved, it is therefore necessary to use the contraction of concrete under a kind of novel test method reacting drying environment, thus
Assess the ability of its early stage cracking resistance.
