Device name: ASTM1581-Shrinkage Ring Restricted Detector
Model:YC-1581
Origin:Beijing
Purpose:To evaluate the cracking risk of concrete through quantitative analysis
通過定量的分析來評價混凝土的開裂風(fēng)險,并且此方法可操作性強(qiáng),重復(fù)性強(qiáng),適用范圍也比較廣。解決平板法只能部分、不均勻的約束混凝土的收縮變形,而且試驗(yàn)結(jié)果對試件尺寸、材料特性、環(huán)境狀況等的依賴性很大,裂縫的產(chǎn)生無規(guī)律的問題。
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.
