Workload it is very heavy.Simultaneously because frequently moving test specimen, it is easy to break gauge head, test specimen is caused to be scrapped.
During actual test, the pre-buried gauge head in both ends of general horizontal concrete self-constriction instrument and concrete sample is more difficult
Alignment, or because the slight change of test specimen placing direction can cause the large change of measured value, therefore and the error amount of generation has
It can exceed that concrete self-shrinkage value, numerical value is caused to be distorted.
In previous self-constriction test operation, general test age is 1 day, 3 days, 7 days, 14 days, 21 days, 28 days, 28 days
Surveyed later for 1 month primary, the sampling interval is long, be unable to the self-constriction deformation of full lifetime tracking concrete, accidental error for
The influence of sampling curve is bigger.One group of self-constriction test need to carry out 3 pieces of test specimens simultaneously, when carrying out array test, using sleeping
When formula concrete self-shrinkage instrument, comparator test, batch test need to expend much manually moves sample back and forth, expends people
Work.
