description: # Experimental data for chloride diffusion coefficient of concrete by
 rapid chloride migration test The aim of this study is to investigate the
 inuences of cement types on chloride diffusion coefficient of concrete and
 develop a prediction model for chloride diffusion coefficient of concrete
 in terms of material parameters including "Type of cement",
 "Amount of fly ash", "Amount of slag", “Grade of fly
 ash” , “Grade of slag” , “Test method ” and "Water-binder
 ratio". ### **Description of the data and file structure** The
 dataset contains a total of 8 tables and 1270 sets of data. Tables 1 and 2
 provide experimental data for ordinary concrete (OPC). Table 3 and Table 4
 are the experimental data of concrete mixed with fly ash (FA) and slag
 (SG). Table 5 is the experimental data of concrete mixed with fly ash
 (FA).Table 6 is the experimental data of concrete mixed with slag .Table 7
 is the constant voltage RCM data for ordinary concrete.Table 8 is the
 variable voltage RCM data for ordinary concrete. **Variables and
 Definitions in tables 1~8** **Reference**: represents the reference of the
 data source **Type of cement**: represents the type of cement in concrete
 which include POP, and P PO: represents ordinary Portland cement accorded
 with by China's GB/T 175-2007 P, P: represents Portland cement
 accorded with by China's GB/T 175-2007 32.5, 42.5, 42.5R, 52.5,
 52.5R: represent the strength grade of cement accorded with by
 China's GB/T 175-2007 **Amount of fly ash**: represents the amount of
 fly ash (as a percentage of the mass of the cementitious material)
 **Amount of slag**: represents the amount of slag (as a percentage of the
 mass of the cementitious material) **Water-binder ratio**: refers to the
 ratio of the water consumption per cubic meter of concrete to the amount
 of all cementitious materials used. **Chloride diffusion coefficient**:
 tested by the rapid chloride migration test (RCM) at the reference period
 of 28 days collected from reference based on the following criteria:
 cement type are the ordinary Portland cement (OPC) or the Portland cement
 (PC); **Grade of fly ash**: represents the quality grade of fly ash in
 accordance with the Chinese standard GB/T 1596 "Fly ash for use in
 cement and concrete" 1：represents the quality grade of fly ash is
 class1 2：represents the quality grade of fly ash is class2 **Grade of
 slag**: represents the quality grade of slag in accordance with the
 Chinese standard GB/T 18046 "Ground granulated blast furnace slag
 used for cement, mortar and concrete"\ S75：represents the quality
 grade of slag is S75\ S95：represents the quality grade of slag is S95
 S105：represents the quality grade of slag is S105 **Test method**:
 represents the RCM test adopted to measure the diffusion coefficient of
 concrete is categorized into two method: the constant voltage method and
 the variable voltage method " \ variable voltage RCM：represents the
 method should comply with GB/T 50082 and NTBUILD-492\ constant voltage
 RCM：represents the method should comply with the IBAC method of
 Germany's Anchen University of technology and JTG/T B07-01-2006 This
 database collects the chloride ion diffusion coefficient measured by RCM
 method (including the method adopted by the Nordic standard NT Build 492,
 the IBAC method of Germany's Anchen University of technology, as well
 as the methods adopted by China's GB/T 50082-2009 and JTG/T
 B07-01-2006); The curing method is standard curing. **Version changes**
 13-may-2024: Table 5 was added into the file "Experimental data for
 chloride diffusion coefficient of concrete by rapid chloride migration
 test.xls", which includes 209 sets of test data for the chloride
 diffusion coefficient of fly ash concrete. 10-sep-2024: After
 verification, 13 sets of duplicate chloride diffusion coefficient test
 data for fly ash concrete were removed from Table 5 in the file
 "Experimental data for chloride diffusion coefficient of concrete by
 rapid chloride migration test.xls". 14-jan-2025: Table 6 was added
 into the file "Experimental data for chloride diffusion coefficient
 of concrete by rapid chloride migration test.xls", including 223 sets
 of test data for the chloride diffusion coefficient of slag
 concrete. Tables 7 and  8 were added into the file "Experimental data
 for chloride diffusion coefficient of concrete by rapid chloride migration
 test.xls", including 99 and 153 datasets for the chloride diffusion
 coefficient of ordinary concrete respectively. The RCM test adopted to
 measure the diffusion coefficient of concrete is categorized into two
 method: the constant voltage method and the variable voltage method. The
 constant voltage method should comply with the Chinese standard JTG/T
 B07-01-2006 and the IBAC method of Germany's Anchen University of
 technology. The variable voltage method should comply with the Chinese
 standard GB/T 50082 and Nordic standard NTBUILD-492 . The data presented
 in Table 7 and Table 8 further differentiate the RCM testing
 methodologies. Specifically, Table 7 employs the constant voltage RCM
 method, whereas Table 8 utilizes the variable voltage RCM method.
