Data relating to work concerning the development of a quaternary cementitious system for aerial additive manufacturing

Data collection method:

Extrusion and deposition data were collected by observation and manual recording. Mechanical tests were carried out on an Instron Universal 2630-120/305632. Settlement tests compressed material at a rate of 2 mm/minute. Four-point bending flexural tests were in accordance with British Standard BS EN 12390-5:2009 (BSI,2009). Compressive tests were subsequently conducted in line with British Standard BS EN 1015-11:1999 (BSI, 1999). Rheometer tests: A TA DHR-2 rheometer was used to conduct the tests with a 25 mm diameter flat upper geometry plate and flat 40 mm diameter lower plate. Flow tests were shear stress-controlled using linear stress ramps ranging from 300 - 6000 Pa and 900 - 50000 Pa. Oscillation tests were conducted over a period of 2000 seconds, covering the open time of the OPC/PFA/CAC/CS mixes and were controlled using an angular displacement of 5x10−5 radians with frequency maintained at 1 Hz. Calorimetry tests: mixes were placed in a Calormetrix I-Cal 4000 isothermal calorimeter immediately following mixing and vibration. Each mix was tested three times, with the chamber temperature maintained at 7°C, 14.5°C and 22°C respectively. Tests were carried out over a period of forty eight hours.

Technical details and requirements:

Data was created in the software of the laboratory instruments but all were imported into Microsoft Excel; the Excel files contain all relevant data for the work.

Additional information:

Microsoft Excel was used for data organisation and analysis and Microsoft PowerPoint for figures exported to PDF for use in LaTeX.
