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

Recently, the supply and demand of aggregates has become difficult due to various practical constraints such as depletion of natural aggregate resources and tightening environmental regulations. As a result, aggregates such as selective crushed aggregates and river aggregates are now distributed to the construction market. In particular, among the aggregates distributed in the country, selective crushed aggregates that have been used recently are characterized by the fact that the quality of the raw material is not uniform and is based on geological characteristics. Such bad aggregates can affect the overall performance of the concrete and shorten the life of the structure. Therefore, in this study, in order to improve such problems, we want to analyze the effect of aggregate powder on mortar.
