In this study, we examined the physical properties of cement mortar by replacing a part of the amount of fine aggregate in moist mud flat. I analyzed the possibilities of using bricks. Flow measurement results show that the flow value increases as the mixing ratio of cement and fine aggregate increases and the flow value decreased as the replacement ratio of moist mud flats decreased. Chloride contents were also found to decrease with decreasing substitution rate of moist mud flats. As a result of the compressive strength measurement, the compressive strength increased in inverse proportion as the displacement ratio of moist mud flats decreased in most mixing ratio. As a result of tensile strength measurement, the tendency was similar to compressive strength and the intensity increased as the replacement ratio of moist mud flats decreased.
