The Effect of Soil on the Fundamental Properties of Low Strength Mortar in Fine Aggregate

잔골재 중 토분이 저강도 모르타르의 기초적 특성에 미치는 영향

Recently, the use of selective crushed aggregates is increasing due to the supply and demand shortage of aggregates. In the case of selective crushed aggregates, aggregates are produced using soil, rocks, etc., mainly generated at construction sites as raw materials. As a result, the quality of the raw material may not be uniform and may contain a large amount of soil. In the case of using such a bad aggregate shortens the life of the structure, there is a fear that adversely affect the overall performance, such as the strength and durability of the concrete. Therefore, this study analyzes the effect of aggregate soil on mortar in the low-strength mortar and ultimately proposes the regulation value of clay content in the soil content of crushed aggregates such as crushed aggregates.
