As urbanization progressed along with quantitative expansion of the construction industry, concrete has developed diversely as a material that is the most extensively used in the construction industry. However, aggregate resources that are an essential element of concrete production are gradually being depleted and the phenomenon of aggregate shortage has been intensifying due to the reinforcement of regulations on environmental issues. Therefore, in the present study, environment friendly mortar was made by replacing aggregate with mud that is dumped when dredging sand is dumped. To identify the dynamic characteristics of the mortar and to identify its fire resistance efficiency, the mortar was heated and its residual compressive strength was measured. In the results, the residual compressive strength values of MM1, MM2, and MM3 were 45%, 95%, and 57.7% respectively and the mix MM2 showed the highest fire resistance efficiency.
