Device name： ASTM1581-Shrinkage Ring Restricted Detector
Model：YC-1581
Origin：Beijing
Purpose：To evaluate the cracking risk of concrete through quantitative analysis

The cracking risk of concrete can be evaluated by quantitative analysis.  ASTM C1581 provides us a method which is operable, repeatable and widely applicable. The problem of the plate method, such as shrinkage deformation of partially and unevenly confined concrete and the test results depending on the size, material characteristics, environmental conditions, etc. of the sample, and irregular cracking are all solved.
