Conclusion • Eucon 2 ml has an optimal flowability, set time, and compressive strength.

Conclusion • Eucon 2 ml has an optimal flowability, set time, and compressive strength. • Most of the other superplaciticizers has a retarding effect on the mortar. • Future research may include printing methods or manipulating proportions to make a more efficient mix.

Deliverables • Continue mixing different mixes using the different chemicals • Analyze the finalized

Deliverables • Continue mixing different mixes using the different chemicals • Analyze the finalized data to find best mix • Use the optimal mix to use the mortar gun for 3 D printing • Prepare and finalize publication
