Abstract |
This study investigated the effects of blast furnace slag mortars activated with sodium hydroxide(NaOH) and gypsum in relation to flow, setting time and compressive strength. The parameters in this studied was the gypsum ratio 0 to 50%, 3M and 6M of activator concentration and 20±2℃ and 35±2℃ of curing temperatures. The results of flow was increase, setting time was increase as the amount of gypsum increases. But the results of compressive strength was dependent on the gypsum ratio, indicating that the compressive strength increased with the increase of the amount of gypsum until a certain limit, beyond which the strength decreased quickly.
