The present invention has simple and rational structure, easy operation, convenient installation and adjustment, and short test period; and is applicable to industrialized large-scale production.
Description
Technical field
The present invention relates to building materials durability test technical field, be specifically related to a kind of can the actual engineering of simulation test in salt solusion in concrete, transmit and produce the test unit that the salt crystal erosion destroys, particularly a kind of concrete salt-resistant solution physical crystal erosion destruction performance proving installation.
Background technology
The test and evaluation of concrete durability is unusual complicated problems, owing to the reason difference that causes that concrete durability destroys, the method that is used for the concrete permanance of test and evaluation is also different with index, and salt solusion is one of major reason that causes concrete durability destruction to concrete physical erosion.At present, having the scholar to adopt both at home and abroad changes as the index of estimating the anti-salt crystal erosion of concrete performance (these evaluation indexes mainly all are that the evaluation index according to the chemical erosion of concrete material sulfate resistance gets) the wet round-robin method of concrete dry and compressive strength, rupture strength or concrete dynamic modulus of elasticity, but this method can not really be simulated actual salt crystal erosion process, and workload is big, time is long, data are more discrete, so also there is bigger dispute in the use of this method and evaluation index.The salt crystal erosion destroy be cause the xoncrete structure premature failure key factor it, experimental test and evaluation method that research and development science, reliable concrete salt crystal erosion destroy have become an important ring that solves concrete crystal erosion destruction, also are one of emphasis of relevant scholar's research.
Summary of the invention
The object of the present invention is to provide a kind of measuring technology of concrete material permanance, at the problem that exists in current concrete salt-resistant solution physical erosion damage method of testing and the evaluation index, invented the concrete salt-resistant solution physical crystal erosion destruction performance proving installation of short evaluation concrete salt-resistant solution crystal erosion performance of a kind of easy to use, cycle.
Purpose of the present invention is achieved by following technical proposals: include the sealable organic glass box that certain thickness high-strength organic glass is processed into, vacuum pump and decompressor, described organic glass box, decompressor, vacuum pump connects successively by pipeline, be provided with the groove that is communicated with and is full of salt solusion with external reading tube in described organic glass box bottom, with the organic glass box, the pipe ends that vacuum pump links to each other respectively is provided with a valve, described vacuum pump is provided with tensimeter, be provided with the organic glass cover plate and the bolt of fixing concrete test specimen in the organic glass box, be provided with the O-ring seal that contacts sealing with concrete sample in the groove of organic glass box bottom, described groove is circular.
Principle of work of the present invention is sketched in following:
At first, concrete sample is installed, inject a certain amount of salt solusion by reading tube, close and open the sealing property that each drives the valve proving installation then respectively, and on reading tube, read initial scale, open vacuum pump then and regulate atmospheric pressure in the organic glass box by decompressor, and remain under certain environment under low pressure, reduce the relative humidity in the organic glass box, read reading on the reading tube to the regular hour, then difference by twice reading and time can calculate the quantity and the salt solusion that enter salt solusion in the concrete and enter concrete speed.Can also make the relative humidity in the organic glass box do cyclical variation by regulating decompressor, further test the relative humidity condition when changing thereby repeat above-mentioned testing procedure, salt solusion enters concrete correlation parameter.
Under certain relative humidity condition, perhaps under the relative humidity cyclical variation condition, enter quantity and the transfer rate of salt solusion in concrete in the unit interval in the concrete with salt solusion in the certain hour, two indexs are estimated the resistance that concrete destroys the salt solusion physical crystal erosion.By above-mentioned experimental test, can simulate the performance of the anti-salt crystal erosion of actual engineering specifications test concrete.
Advantage of the present invention is: 1) this device can quantitatively obtain the concrete in different porosities and aperture under different relative humidity and air pressure conditions, salt solusion enters concrete quantity by capillary action, and can calculate the speed 2 that capillary rises) can simulate under the physical condition salt solusion and rise by capillary and enter concrete process, compare with the present method of testing of drying and watering cycle of using, this device is more near actual conditions, data are more reliable, workload significantly reduces, and has more reduced personal error; 3) simple to operate, the concrete that test needs is few, can test from the practice of construction on-site sampling; 4) the method performance that anti-salt crystallization is invaded to concrete that salt solusion capillary rise height and the crystallization of calculating salt solusion are pressed in the concrete of employing test is first estimated.In sum, the present invention is simple and reasonable, simple to operate, installation is easy to adjust, test period short, is suitable for industrialized production.
