This paper presented the application of gold mining waste which is called "tailing" as the substitution material of fine aggregate in the hot rolled sand sheet. Several amounts of tailing are substituted to modify the gradation of the fine aggregate. The gradation analyses are conducted to evaluate the effect of the substitution of tailing on the gradation distribution of the mixed material. The Marshall tests are also conducted to asses the impact of tailing substitution on the strength of the hot rolled sand sheet. The gradation analysis shows that the substitution of 50% tailing has a significant effect on the distribution of mixed materials. The coefficient of uniformity, Cu and coefficient of curve, Cc of 4.82 and 1.72 are obtained, respectively. The mechanical test results using the Marshall test shows that the substitution of 50% tailing brings about a significant improvement in the strength of the hot rolled sand sheet. The strength of hot rolled sand sheet increase 100% or 2-fold higher compared than those without the tailing is obtained. The results of this study have indicated that the gold mining waste of tailing may be viable as the substitution material in the hot rolled sand sheet.
