Automatic acquisition multichannel accelerated attack test device for measuring anti corrosion capability against chloride ion

Abstract

The invention relates to an automatic acquisition multi-channel accelerated corrosion test device for measuring the capability against the erosion of chloride ions. A common three-electrode potentiostat is utilized to form a set of device system capable of synchronously measuring a plurality of test samples and automatically recording test data through an integrated circuit, a software and an electrolytic bath which are integratedly and independently developed. The device overcomes the defect that the quantity of the test samples for accelerated corrosion tests at home and abroad is limited by channels of the potentiostat, greatly saves test cost, enlarges test scale, and saves test time. The invention has convenient and simple use, and provides the low-cost and high-efficiency test device for evaluating the capabilities of cement-based grout materials and concrete materials against the erosion of the chloride ions.

Description

technical field [0001] The invention relates to the relevant technical field of construction material detection, in particular to an automatic collection multi-channel accelerated corrosion test device for measuring the chloride ion erosion resistance of cement-based grouting materials and concrete materials. Background technique [0002] In recent years, the problem of tendon corrosion in post-tensioned structures has become more and more serious. During construction, after tensioning the steel strands, grout is used to pour into the prestressed pipes to fill the gaps in the prestressed pipes. Grouting provides an alkaline protective barrier for the prestressed tendons, and makes the prestressed tendons and concrete well combined to ensure the effective transmission of prestress between them. The compressed concrete around the prestressed tunnel is the initial barrier to prevent the intrusion of corrosive elements, while the grout is the last line of defense against the in...
