Experimental Data set for concrete compressive strength prediction from IIT Bhubaneswar concrete laboratory

The database is gathered by experimental testing concrete cube specimens, in the concrete technology laboratory of the Indian Institute of Technology Bhubaneswar, for 188 different concrete mixes. Several concrete mix proportions are tested for predicting the compressive strength of recycled aggregates concrete (RCA). For most of the mixes, coarse recycled aggregates were used as the only coarse aggregate for concrete mix testing. It includes a variation of water/binder in ranges of 0.25 – 0.75; addition of fly ash, Ground Granulated Blast-furnace Slag (GGBS), and metakaolin (MK) to the concrete mix.

本数据集通过在印度理工学院布巴内斯瓦尔分校混凝土技术实验室开展混凝土立方体试件试验采集得到，共包含188组不同配合比的混凝土试样。本次试验针对再生骨料混凝土（Recycled Aggregates Concrete, RCA）的抗压强度预测需求，对多组混凝土配合比进行了测试。绝大多数试样仅以再生粗骨料作为混凝土的唯一粗骨料开展试验。该数据集涵盖水胶比范围为0.25~0.75的多种配比，同时包含在混凝土中掺入粉煤灰、粒化高炉矿渣粉（Ground Granulated Blast-furnace Slag, GGBS）与偏高岭土（metakaolin, MK）的组别。
