    Abstract

    The potential of treated Sidoarjo Mud as pozzolanic material has been investigated previously with positive results by applying heat treatment by burning it at high temperature. This study focusses on the influence of heating temperature, particle fineness or nominal size and cement replacement ratio of treated Sidoarjo mud in mortar. The treated Sidoarjo mud was characterized by a series of test of Thermal gravimetric Analysis (TGA), X-Ray Diffraction (XRD) and X-Ray Fluorescence (XRF). The heating temperature variation applied were at 500, 600, 700, and 800°C for two hours, and oven dried but untreated sample for comparison. The particle sizes were varied by sieving passing size 600-150, 150-75, and <75μm, while the percentage of cement replacement ratio was of 10, 20, and 30 by mass. The results show that the burned mud at 600°C, fineness <75µm, and replacement ratio 10 produce highest compressive strength. Heating the mud at 500-800°C would make it become pozzolanic whereas the unburned mud is not eligible to be used as pozzolanic material
