Cleaned Metadata Set for ML

The dataset consolidates 460 experimentally validated concrete mixes collected from 30 peer-reviewed studies, harmonized into a unified format with consistent units, treatment descriptors, curing details, and mechanical performance indicators. All seven RCA treatment categories are explicitly encoded, along with mix proportions and testing conditions, enabling full replication of the machine learning workflow and facilitating future benchmarking studies本数据集整合了从30篇同行评审研究中收集的460组经实验验证的混凝土配合比，将所有数据统一为标准化格式，采用一致的计量单位、处理方式描述、养护细节及力学性能指标。本数据集明确编码了全部7类再生粗骨料（Recycled Coarse Aggregate, RCA）处理类别，并涵盖配合比参数与试验条件，可完整复现机器学习工作流程，亦可为后续基准测试研究提供便利。
