The purpose of this experimental study is to increase the strength of mortar mixed with activated Hwang-Toh (AHT) and granulated blast furnace slag (GGBS) as a compound for the development of eco-friendly concrete. The compressive strength test was carried out by making mortar specimens with a certain ratio of AHT and GGBS. The percentage of AHT were at 30% and 50% and the GGBS were a 40% and 50% as Major variables. The results of this study showed that for specimens with percentage of AHT at 30% with GGBS increased above the strength of the mortar without the binding. However, the compressive strength of experimentation with percentage of AHT at 50% with partially replace GGBS has decreased by more than the mortar without the binding. Therefore, further study is deemed necessary.
