波纹管法自收缩测定仪（ASTM C1698） 返回列表页

Device name ：Apparatus for autogenous strain of cement paste and mortar in a corrugated PE-tube
Model：YC-BWS
Origin：Beijing
Purpose：To measure automatically the autogenous strain of cement paste and mortar 

该产品根据美国标准ASTM C1698-09研制，并优于标准要求，主要部件包括刚性支架、标准杆、电子千分表和波纹管，可将试样的体积变形转化为线性变形，能够避免试样在测试过程中出现水分散失，主要用于自动测量水泥浆体和砂浆的自收缩和膨胀的变化情况。 
骨料粒径：4.75mm
The product is developed according to ASTM C1698 and is superior to the standard requirement. The main components include three dilatometer benches, a reference bar, three length measuring gauges and some corrugated plastic tubes. The volume deformation of the sample can be transformed into linear deformation, which can avoid water loss in the test process. It is mainly used to automatically measure the autogenous strain of cement paste and mortar.
Maximum aggregate size：4.75mm
