As the aggregate supply and demand shortages in Korea due to the lack of aggregates due to the regulation of production and use conditions of domestic aggregate collectors, the media recently pointed out the distribution of so-called bad aggregates containing soil powder. Such poor aggregates have a high self-absorption rate according to the reference, etc., leading to a decrease in the fluidity of the concrete. Therefore, in order to secure fluidity, the unit quantity increases greatly from 30 kg/㎥ to 55 kg/㎥, and the increased unit yield eventually leads to a decrease in compressive strength, resulting in a decrease in strength from about 35 % to 45 % compared to general aggregates. It indicates that there is a risk of shortening the life of the structure. Therefore, this study aims to analyze the effect of aggregate soil on concrete.
