Experimental data for chloride diffusion coefficient of concrete by rapid chloride migration test

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., In order to investigate the influences of cement types on chloride diffusion coefficient of concrete, a total of 1270 sets of experimental data of chloride diffusion coefficient (DRCM;28) tested by the RCM method at the reference period of 28 days were collected from reference based on the following criteria: cement type are the ordinary Portland cement (OPC) or the Portland cement (PC); 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., , # 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 ordin...本数据库收录了采用快速氯离子迁移（RCM）法测得的氯离子扩散系数，测试方法涵盖北欧标准NT Build 492规定方法、德国安琴工业大学IBAC法，以及中国GB/T 50082-2009与JTG/T B07-01-2006规定的测试方法；试样养护方式为标准养护。为探究水泥类型对混凝土氯离子扩散系数的影响，本数据集基于以下筛选标准，从公开文献中收集了共计1270组28d龄期（基准测试龄期）下RCM法测得的氯离子扩散系数（DRCM;28）实验数据，筛选规则为：水泥类型为普通硅酸盐水泥（OPC）或硅酸盐水泥（PC）。 # 快速氯离子迁移法测试混凝土氯离子扩散系数实验数据 本研究旨在探究水泥类型对混凝土氯离子扩散系数的影响，并基于水泥类型（Type of cement）、粉煤灰掺量（Amount of fly ash）、矿渣掺量（Amount of slag）、粉煤灰等级（Grade of fly ash）、矿渣等级（Grade of slag）、测试方法（Test method）以及水胶比（Water-binder ratio）等材料参数，构建混凝土氯离子扩散系数预测模型。 ### 数据与文件结构说明 本数据集共计包含8张数据表与1270组实验数据。其中，表1与表2为普通硅酸盐水泥（OPC）配制的普通混凝土实验数据；表3与表4为掺粉煤灰（FA）与矿渣（SG）的混凝土实验数据；表5为掺粉煤灰混凝土的实验数据；表6为掺矿渣混凝土的实验数据；表7为普通混凝土的恒压RCM测试数据；表8为普通混凝土的变压RCM测试数据。
