Description

The migration evaluation methodology of chloride ion in a kind of Binder Materials containing villaumite
Technical field
The present invention relates in a kind of Binder Materials containing villaumite chloride ion migration evaluation methodology.
Background technology
There is component in corrosive ion, and all ocean engineerings in ocean engineering all in different water levels, have certain Effect of water pressure, so ion has ion migration in concrete component, when the surface of reinforcing bar in ion migration to component, Then steel bar corrosion being produced, thus destroying component, the stable of structure and safety being impacted.So ion is in Binder Materials Transport to research ocean engineering in concrete durability extremely important.But migration in Binder Materials for the ion is one Individual very long process, the test period is very long, for this reason, a lot of ways are to promote ion using the alive method of concrete at present Concrete is migrated.But, the species of different Binder Materials, hydrated product is different, the ionic speciess in hole solution And quantity is also different, in the presence of voltage, due to the difference of electrical conductivity, cause different types of Binder Materials each other There is no comparability.
Content of the invention
It is an object of the invention to provide one kind is subject under hydraulic pressure effect in marine environment, chloride ion migrates in Binder Materials Device and chloride ion transport rule evaluation methodology.
The technical solution used in the present invention is:
The migration evaluation methodology of chloride ion in a kind of Binder Materials containing villaumite, processes glue containing villaumite using hydraulic pressure pressurization moving apparatus Gel material test specimen, to the test specimen section after pressurization, measures the concentration of chloride ion.
Described pressurization moving apparatus include water tank, air compressor machine, test specimen erecting device and pipeline, described water tank and pneumatics Machine passes through pipeline and is connected, and air compressor machine is connected by pipeline with test specimen erecting device.
Described moulding pressure scope is 0.1 ~ 1.5Mpa.
The invention has the beneficial effects as follows:
The present invention is pressurizeed to the water in manometer tube by air compressor, by the press water in water tank, test specimen is pressed Power is permeated, and after reaching regulation age, carries out uniformly slicing to test specimen, the chlorine ion concentration gradient of each of sampling and testing after process, The Binder Materials of chloride ion can be contained in its internal migration with effective evaluation, the reality of ocean engineering Service Environment can be more conformed to Border situation, can realize the effective evaluation of Transport in Binder Materials for the chloride ion in the short time in laboratory again.This evaluation Method can effectively shorten and is not pressurized longer problem of slow migration led to test period, avoided using hydraulic pressure migration Although voltage shifts lead to the Binder Materials more than ion concentration to have the reasonable permeability but too fast situation of migration velocity.
