| Abstract | Molten iron desulphurization slag (DS) is a common industrial waste in Taiwan, with chemical constituents similar to Portland cement, high pH value, high calcium oxide and low heavy metal contents. DS has been considered serving as an alkaline catalyst to pozzolanic reactions with the mixture of granulated blast furnace slag (GBFS) powders. In this paper, we focus on using DS and GBFS powders as binders to produce mortar without Portland cement. Material properties and the microstructure of the constituents were examined. The fresh behaviors, hardening properties and microstructure of the mortar are also investigated. The test results show that DS can provide sufficient alkali condition for GBFS to activate pozzolanic reactions. The compressive strength of the mortar can reach 17MPa at 28 days of age. A linear proportion between the amounts of DS and water is also found in the flow test. Increasing the amount of GBFS can shorten the setting time; while increasing the DS amount can shorten the time interval between the initial and final setting. |
