According to the durability test of concrete

and in order to meet the requirements of stress loading affected on concrete by multi coupling factors

a new loading device which takes account of ion erosion concrete under multi coupling factors was designed

made

and used to test the durability of concrete. The new device adopted the advantages and avoided the disadvantages of existing devices in China and foreign countries. The test results show that the new device has many excellent characteristics such as high loading accuracy

small stress losses

simplicity of operation

low cost and can be used for lots of test. The new device has gained national patent certificate of China

and may provide references for the research of concrete durability
