10-year natural carbonation of concretes with limestone, flyash, volcanic ash, and slag and exposed to tropical climate in India

The data set includes the concrete properties and natural carbonation depths of 45 different concretes exposed to tropical climate in India. There are three sets of data. Set A contains information about the mix proportions, including the type of cement, water-to-binder ratio (w/b), the amount of binder, the percentage of SCM replacement, the amount of sand and gravel, and the air content in the concrete. Additionally, 28 days of compressive strengths (fc) with curing duration is provided. Set B contains the natural carbonation depths of concrete exposed to sheltered conditions, and Set C consists of the natural carbonation depth of concrete exposed to unsheltered conditions. In brief, the data set will provide the material properties of 45 different concretes and their natural carbonation depths exposed to sheltered and unsheltered conditions with exposure duration in years.

本数据集涵盖了印度热带气候环境下45种不同混凝土的材料性能与自然碳化深度数据，共分为三组。A组包含混凝土配合比相关信息，具体包括水泥类型、水胶比（water-to-binder ratio, w/b）、胶凝材料用量、辅助胶凝材料（Supplementary Cementitious Materials, SCM）掺量、砂石用量及混凝土含气量；此外，还提供了28天抗压强度（fc）与养护龄期的相关数据。B组收录了遮蔽环境下暴露混凝土的自然碳化深度数据，C组则收录了无遮蔽环境下暴露混凝土的自然碳化深度数据。简言之，本数据集提供了45种不同混凝土的材料性能，以及它们在遮蔽与无遮蔽环境下的自然碳化深度，并附带以年为单位的暴露时长数据。
