Minimum and maximum compaction of RCA–TDA mixtures

This dataset contains laboratory test results for waste-derived granular geomaterials composed of recycled concrete aggregate (RCA), tyre-derived aggregate (TDA), and their mixtures with rubber contents of 0, 11, 23, 55, and 100% by weight. The file contains data for 5 mixtures, including soil specific density, assumed soil moisture content, soil mass in the cylinder at maximum and minimum compaction levels, and soil volume in the cylinder at maximum and minimum compaction levels. These measurements were used to analyze the minimum and maximum dry densities and the corresponding minimum and maximum void ratios, calculated according to standard geotechnical formulas.

本数据集包含由再生混凝土骨料（recycled concrete aggregate, RCA）、轮胎衍生骨料（tyre-derived aggregate, TDA）及其混合料制备的废弃源粒状土工材料的实验室试验结果，其中混合料的橡胶掺量按质量计分别为0、11、23、55和100%。该数据集文件包含5组混合料的相关数据，具体包括土的比重、假定土样含水率、最大与最小压实状态下圆筒内的土样质量，以及对应状态下圆筒内的土样体积。上述实测数据被用于分析最小与最大干密度及对应的最小与最大孔隙比，相关计算依据标准土工公式完成。
