Device for controlling concentration of erosion solution in concrete durability experiment

Abstract

The invention discloses a device for controlling the concentration of an erosion solution in a concrete durability experiment, which comprises a buffer slot (1), a circulating pump (2), an experiment environment box (3), a titrating pump (4), a measuring slot (5), a controller (6), a recovering slot (9) and valves, wherein the buffer slot is communicated with an ion replenishing valve (7) and a water replenishing valve (8) and is communicated with the experiment environment box through the circulating pump; the experiment environment box is connected with the measuring slot through the titrating pump; the controller is connected with the measuring slot through a measuring electrode and is connected with the ion replenishing valve and the water replenishing valve through data lines; and the recovering slot (9) is connected with the experiment environment box through a liquid discharging valve (10). The device for controlling the concentration of the erosion solution in the concrete durability experiment is used for automatically regulating the concrete durability experiment to simulate the concentration of harmful ions in the erosion solution in the experiment environment box, thereby ensuring that the concentration of the harmful ions in the environment of specimens used in the concrete durability experiment is stabilized in the set range. The invention achieves the online control of the concentration of the erosion solution and increases the function of the concrete durability experiment.

Description

technical field [0001] The invention relates to the field of concrete durability research, in particular to a method for automatically adjusting the concentration of an erosion solution in a concrete durability research test, performing state constraint simulation, temperature / humidity environment adjustment, and harmful medium erosion on concrete specimens. Provide a research platform for the durability test of concrete structures. Background technique [0002] Concrete structure is currently the most widely used structural form. The number of structural projects with concrete structures as the main body in service in my country occupies an absolute dominant position, and there are durability damage characteristics of "rust in the south and freezing in the north". The durability of major concrete structures has not been perfectly solved in theory. The concrete structure is affected by the service environment, and some defects will cause cracks to form, cracks to expand, and...
