| Abstract: | Based on the USB bus of computer system and virtual instrument method, multipurpose chlorine ion penetration resistanee of eonerete measuring instrument was developed. This instrument can follow the ASTM C1202-97 speeifieation and NEL method whieh is based on the Nerust- Einstein prineiple to test the coulomb passed during a speeifie time interval and ehlorine ion diffusion eoefficient of eonerete, and finally based on those results to evaluate the ehlorine ion penetration resistanee of eonerete. Experiment results show that this instrument ean follow the aforementioned speeifieation and method to aeeurately evaluate the ehlorine ion penetration resistanee of eonerete, at the same time, this instrument has the eharaeters of high seeurity, good transplantability and strong extensibility. |
