The device that lower concrete expansion rate measures.Therefore, Accurate Determining limited expansion rate to swelling agent in expansive concrete
In application it is critically important.
GB23439-2009《Cement expansive material》In define a kind of measure and mix the limited expansion rate of swelling agent concrete
And the equipment and assay method of limitation contract with dry rate, this equipment and assay method have the disadvantage that：First, it can not carry out underwater
The measurement of concrete expansion rate；Second, test data is the time point data of each age, can not while maintenance while follow-on test；
Third in each test process, needs multiple suppressed zero, and test block is put in repeatedly lift, and manual operation is cumbersome；4th, to concrete
Test block surface clean-up performance is more demanding, and clean-up performance directly affects the accuracy of test；5th, concrete test block is molded
Process is more demanding, once there is uneven or losing fangle or non-standard cuboid with equipment contact surface in concrete test block
When, limited expansion rate test accuracy will be greatly affected；6th, test process consumption manpower is more, needs two people to coordinate and completes,
A wherein people is responsible for controlling test block, and another people is responsible for controlling amesdial gauge head.
Current limited expansion rate test equipment and method there are disadvantages described above, cause to test continuity is poor, operation compared with
Complexity, manpower consuming is more, test accuracy is poor, is unable to measure the problems such as underwater concrete expansion rate, therefore, is badly in need of a kind of
Can be underwater on the water, continuous detection, the concrete limitation that test accuracy is good, easy to operate, test process is without manual intervention
Expansion rate sensing equipment.
