Highlights MgO-to-MS mole ratio and water-to-solid (w/s) weight ratio influence MOS setting time. Larger MgO-to-MS mole ratio corresponds to a higher compressive strength. Compressive strength decreases and weight loss increases as w/s increases. Larger gel pores and smaller average pore diameter cause higher compressive strength. MOS setting time = 33 min, spread fluidity = 60 mm; MOS can be used for 3D printing.
Abstract The mechanical properties and setting time of magnesium oxysulfate cement (MOS) were evaluated in the context of three-dimensional printing. MOS samples with MgO-to-magnesium sulfate mole ratios ranging from 2 ~ 9 and four water-to-solid weight ratios ranging from 0.27 ~ 0.57 were developed. The initial and final setting time was ~30 and 40 min, respectively. Moreover, MOS was prepared for 3D printing. The MOS micro-structure was examined. The average pore diameter was less than 20 nm, and the total porosity ranged from 11.76 to 37.39%. The gel pore content (<10 nm) and average pore diameter influenced the MOS compressive strength.
