Abstract

A concrete acid and alkali resistance testing device comprises a host, a concrete reaction chamber, a refrigerating device and a solution circulating water path. A PLC control system serves as the host. The concrete reaction chamber comprises a box body, a heater, a refrigerating tube, a temperature sensor, a concrete test piece supporting plate, a stirrer, a fixed cover and a movable cover. A low-temperature constant-temperature groove serves as the refrigerating device, and low-temperature antifreezing liquid can be sent into the refrigerating tube in a circulating mode. The solution circulating water path comprises a solution tank, an air pressure balancing valve, an impurity tank, an electric drainage valve, an electric blow-down valve, a PPR tube, an electronic water meter and a water pump. The concrete acid and alkali resistance testing device is novel in design, can simulate the PH value and temperature of acid and alkali solutions, and has the advantages of being capable of automatically running, saving energy and protecting the environment, low in failure rate, high in solution purifying capacity and the like. The concrete acid and alkali resistance testing device can play a great role in promoting the development and detection of concrete.

Description

technical field [0001] The invention belongs to the field of concrete detection devices, in particular to a concrete acid and alkali resistance test device, which is suitable for the detection of concrete, hollow bricks, fired bricks and related building materials. Background technique [0002] Concrete is one of the most important civil engineering materials in contemporary times and is widely used in buildings, subways, bridges, roads and pipelines. As concrete is used more and more widely, higher requirements are put forward for concrete. Concrete will be damaged by various factors during use, and concrete determines the service life of the project, so the performance of concrete has been paid more and more attention by people. Both acid solution and alkali solution will have harmful effects on concrete, such as: acidic or alkaline sewage corrosion on bridge piers, acid rain on ground buildings, domestic sewage on underground pipelines, etc. Both acid and alkali can cau...
